The problem you are having with thrift has to do with autoconf and automake
being older versions than work with thrift. I worked around this by
copying the macros from newer installs and adding them to an acsite.m4
file. I've attached the file, so if you just drop it into the root
of the thrift disto it should bootstrap without errors.
Let me know if you have other issues, I've spent the last few weeks
packaging up rpms for thrift and cassandra for centos-5 at work, so
can probably get you over build issues.

# ---------------
# Check whether `mkdir -p' is known to be thread-safe, and fall back to
# install-sh -d otherwise.
#
# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
# created by `make install' are always world readable, even if the
# installer happens to have an overly restrictive umask (e.g. 077).
# This was a mistake. There are at least two reasons why we must not
# use `-m 0755':
# - it causes special bits like SGID to be ignored,
# - it may be too restrictive (some setups expect 775 directories).
#
# Do not use -m 0755 and let people choose whatever they expect by
# setting umask.
#
# We cannot accept any implementation of `mkdir' that recognizes `-p'.
# Some implementations (such as Solaris 8's) are vulnerable to race conditions:
# if a parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
# concurrently, both version can detect that a/ is missing, but only
# one can create it and the other will error out. Consequently we
# restrict ourselves to known race-free implementations.
#
# Automake used to define mkdir_p as `mkdir -p .', in order to
# allow $(mkdir_p) to be used without argument. As in
# $(mkdir_p) $(somedir)
# where $(somedir) is conditionally defined. However we don't do
# that for MKDIR_P.
# 1. before we restricted the check to GNU mkdir, `mkdir -p .' was
# reported to fail in read-only directories. The system where this
# happened has been forgotten.
# 2. in practice we call $(MKDIR_P) on directories such as
# $(MKDIR_P) "$(DESTDIR)$(somedir)"
# and we don't want to create $(DESTDIR) if $(somedir) is empty.
# To support the latter case, we have to write
# test -z "$(somedir)" || $(MKDIR_P) "$(DESTDIR)$(somedir)"
# so $(MKDIR_P) always has an argument.
# We will have better chances of detecting a missing test if
# $(MKDIR_P) complains about missing arguments.
# 3. $(MKDIR_P) is named after `mkdir -p' and we don't expect this
# to accept no argument.
# 4. having something like `mkdir .' in the output is unsightly.
#
# On NextStep and OpenStep, the `mkdir' command does not
# recognize any option. It will interpret all options as
# directories to create.

## Type existence. ##

# ---------------- #
# General checks. #
# ---------------- #
# Up to 2.13 included, Autoconf used to provide the macro
#
# AC_CHECK_TYPE(TYPE, DEFAULT)
#
# Since, it provides another version which fits better with the other
# AC_CHECK_ families:
#
# AC_CHECK_TYPE(TYPE,
# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
# [INCLUDES = DEFAULT-INCLUDES])
#
# In order to provide backward compatibility, the new scheme is
# implemented as _AC_CHECK_TYPE_NEW, the old scheme as _AC_CHECK_TYPE_OLD,
# and AC_CHECK_TYPE branches to one or the other, depending upon its
# arguments.
# _AC_CHECK_TYPE_NEW(TYPE,
# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
# [INCLUDES = DEFAULT-INCLUDES])
# ------------------------------------------------------------
# Check whether the type TYPE is supported by the system, maybe via the
# the provided includes. This macro implements the former task of
# AC_CHECK_TYPE, with one big difference though: AC_CHECK_TYPE was
# grepping in the headers, which, BTW, led to many problems until the
# extended regular expression was correct and did not given false positives.
# It turned out there are even portability issues with egrep...
#
# The most obvious way to check for a TYPE is just to compile a variable
# definition:
#
# TYPE my_var;
#
# Unfortunately this does not work for const qualified types in C++,
# where you need an initializer. So you think of
#
# TYPE my_var = (TYPE) 0;
#
# Unfortunately, again, this is not valid for some C++ classes.
#
# Then you look for another scheme. For instance you think of declaring
# a function which uses a parameter of type TYPE:
#
# int foo (TYPE param);
#
# but of course you soon realize this does not make it with K&R
# compilers. And by no ways you want to
#
# int foo (param)
# TYPE param
# { ; }
#
# since this time it's C++ who is not happy.
#
# Don't even think of the return type of a function, since K&R cries
# there too. So you start thinking of declaring a *pointer* to this TYPE:
#
# TYPE *p;
#
# but you know fairly well that this is legal in C for aggregates which
# are unknown (TYPE = struct does-not-exist).
#
# Then you think of using sizeof to make sure the TYPE is really
# defined:
#
# sizeof (TYPE);
#
# But this succeeds if TYPE is a variable: you get the size of the
# variable's type!!!
#
# This time you tell yourself the last two options *together* will make
# it. And indeed this is the solution invented by Alexandre Oliva.
#
# Also note that we use
#
# if (sizeof (TYPE))
#
# to `read' sizeof (to avoid warnings), while not depending on its type
# (not necessarily size_t etc.). Equally, instead of defining an unused
# variable, we just use a cast to avoid warnings from the compiler.
# Suggested by Paul Eggert.
#
# Now, the next issue is that C++ disallows defining types inside casts
# and inside `sizeof()', but we would like to allow unnamed structs, for
# use inside AC_CHECK_SIZEOF, for example. So we create a typedef of the
# new type. Note that this does not obviate the need for the other
# constructs in general.
