I've added some protection to configure, so you might like to try again
with tomorrow's beta or later.

There are two problems here. The more important one is with your OS, which
seems not to have its X11 stuff correct, so cc is not being found
(and you cannot set it). R's configure has no protection against that.
You can investigate that by
blackduck% touch Imakefile
blackduck% xmkmf
imake -DUseInstalled -I/usr/X11R6/lib/X11/config
blackduck% grep CC Makefile
...
which is what R does. I presume that this will also fail if you compile R
out-of-the-box with gcc? If that works and pgcc does not then something else
in your settings is amiss.
The second is that if you are using a different compiler from that used to
make X11, you may need to set CPICFLAGS etc. But we know about pgcc on Linux
and so these will be set (but not necessarily SHLIB_LDFLAGS: see the R-admin
manual).

Yes cc is empty. Perhaps I should have mentioned that I have set CC=pgcc,
to find the new compiler. Should I be setting cc too? Is there a problem if
the compiler used for X11 was different?
Thanks,
Paul

I am having the xmkmf problem below with todays beta, but I also am
trying to use an new (PGI 6.1), so lots of other things in my setup may
be wrong, and the warning may also be important. Any hints would be
appreciated.
My guess is that this is from
cc=`${srcdir}/tools/GETMAKEVAL CC`
cc=`echo ${cc} | sed "s/ .*//"`
if test "`which ${cc}`" = "`which ${CC}`"; then
shlib_ldflags=`${srcdir}/tools/GETMAKEVAL SHLIBLDFLAGS`
cpicflags=`${srcdir}/tools/GETMAKEVAL PICFLAGS`
fi
cxx=`${srcdir}/tools/GETMAKEVAL CXX`
cxx=`echo ${cxx} | sed "s/ .*//"`
if test "`which ${cxx}`" = "`which ${CXX}`"; then
cxxpicflags=`${srcdir}/tools/GETMAKEVAL CXXPICFLAGS`
fi
in configure and so either your compilers are not set correctly or your
OS's X11 does not find the compilers used to compile it.
I'd start by inserting debugging code in configure at that point to find
out what ${cc} and ${CC} are, with the expectation that one is empty.
