Thanks for the reply, Geoff!  I found the Modules/Setup.dist file and 
copied it to Setup as per your instructions (and the instructions in the 
file).  I also found the following text in the file:

<quote source="Modules/Setup">
# GNU readline.  Unlike previous Python incarnations, GNU readline is
# now incorporated in an optional module, configured in the Setup file
# instead of by a configure script switch.  You may have to insert a
# -L option pointing to the directory where libreadline.* lives,
# and you may have to change -ltermcap to -ltermlib or perhaps remove
# it, depending on your system -- see the GNU readline instructions.
# It's okay for this to be a shared library, too.
</quote>

So I uncommented the line, but my 'make' command failed with the 
following error:

<quote source="make output">
cc -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -no-cpp-precomp -I. 
-I./Include -DHAVE_CONFIG_H   -c ./Modules/readline.c -o 
Modules/readline.o
./Modules/readline.c:21: readline/readline.h: No such file or directory
./Modules/readline.c:22: readline/history.h: No such file or directory
make: *** [Modules/readline.o] Error 1
</quote>

I then rm'd the source tree and re-extracted (to avoid messing with 
config.cache and make clean), and tried adding the -L option described 
in the Modules/Setup script.  My syntax looks like this:

<quote source="Modules/Setup">
readline -L /sw/lib/ readline.c -lreadline -ltermcap
</quote>

But this time my ./configure failed.

My libreadline.* files are located in /sw/lib, they are 
/sw/lib/libreadline.4.dylib, /sw/lib/libreadline.a, and 
/sw/lib/libreadline.dylib.  I am guessing that I am giving the wrong 
syntax for the -L option.  Can anyone see what I'm doing wrong here?

Thank you for your time,


Erik
