This is what I get with a fresh cvs checkout and no libssh2 already
installed:

"simple" is linked to /usr/local/lib/libssh2.1.dylib, but since that
library isn't present it fails to run. In this case, tests/simple is
a binary. If I remove -no-install I get this:
$ make check

Now tests/simple is a shell script with the actual binary in
tests/.libs/simple. This is the script:
#! /bin/sh
# simple - temporary wrapper script for .libs/simple
# Generated by ltmain.sh - GNU libtool 1.5.22 (1.1220.2.365

#
# The simple program cannot be directly executed until all the libtool
# libraries that it depends on are installed.
#
# This wrapper script should never be moved out of the build directory.
# If it is, it will not operate correctly.
# Sed substitution that helps us do robust quoting. It backslashifies
# metacharacters that are still active within double-quoted strings.
Xsed='/sw/bin/sed -e 1s/^X//'
sed_quote_subst='s/\([\\`\\"$\\\\]\)/\\\1/g'
# The HP-UX ksh and POSIX shell print the target directory to stdout
# if CDPATH is set.
(unset CDPATH) >/dev/null 2>&1 && unset CDPATH
relink_command=""
# This environment variable determines our operation mode.
if test "$libtool_install_magic" = "%%%MAGIC variable%%%"; then
# install mode needs the following variable:

The script sets up DYLD_LIBRARY_PATH so that Darwin's linker can find
things. This is definitely a Darwinism needed because of Darwin's
wacky linker. This is with libtool 1.5.22.
Please let me know if I can provide any more information.
