A quick fix is to run the command as follows:

python -- -o @lib.texi `whichlibs`

The "--" causes any getopt I know to stop parsing arguments. But this
doesn't explain why you are getting the wrong getopt().

One theory is that although you're passing the correct -L option, you
haven't built the readline library that comes with Python! Even if
the libreadline.a file is there, it is sometimes (I don't know why
either) necessary to run ranlib on it manually.

It works as follows: the GNU readline library uses xmalloc and
friends. As distributed, these are not in the GNU -lreadline but in
-liberty. The -liberty library also contains other GNU utilities,
amongst which the GNU getopt. Some system admins merge the contents
of -liberty with -lreadline because readline is the only GNU tool they
are interested in. (Try doing a "nm" on the
/usr/(local?)/lib/libreadline.a file to see if xmalloc and getopt are
