Hi again...
	And I just answered my own question.

The reason the above is happening is because your configure found
/usr/include/readline and /usr/lib/libreadline which (on Mac OS X) is
actually the BSD editline or histedit wrapper library (almost readline).
See the symlink from /usr/lib/libreadline.dylib to /usr/lib/libedit.dylib.
The "wrapper" token comes from the version string rl_library_version,
which is something like "EditLine wrapper", and is picked up by the
autoconf test GINAC_LIB_READLINE_VERSION (in ginac.m4).  (This happens to
me with my projects too.  :D )  And since it is AC_DEFINE_UNQUOTED, it
looks like the tokens: EditLine wrapper.
	Solution: if you just want to get going, hand-edit the
generated "config.h" on the lines with *_RL_* with fake readline version
numbers like major.minor = 5.0 or 4.3.
	A real solution requires accommodating the possibility of
non-numeric version string in the config.h header or re-writing the test
so that it is not a problem.

Hope this sheds some light.
