Configuring with 

./configure --with-gcc="gcc -m64 -L/usr/sfw/lib/64 -R/usr/sfw/lib/64" 

where 64bit libreadline is found in /usr/sfw/lib/64, configure script fails to realize that readline lib is present.

I was able to fix the problem by editing config script manually as follows:

$ diff configure~ configure
< if test "$ac_cv_have_readline_readline" = no
> if test "$ac_cv_lib_readline_readline" = no
< echo "$as_me:$LINENO: checking for readline in -ltermcap" >&5
> echo "$as_me:$LINENO: checking for readline in -lreadline -ltermcap" >&5
< LIBS="-ltermcap  $LIBS"
> LIBS="-lreadline -ltermcap  $LIBS"

A proper fix would be to change, but I don't know enough about autoconf to submit a proper patch.

The right solution in this case is to edit Modules/Setup
msg31467 - (view) Author: Alexander Belopolsky (belopolsky) * (Python committer) Date: 2007-03-08 22:25
Can you explain how to edit Module/Setup to solve this problem?

Note that the problem that I see comes before modules are built. In fact it comes even before make.

In any case, I think the check for $ac_cv_have_readline_readline" = no instead of "$ac_cv_lib_readline_readline" = no looks like a typo in  And looking for readline in libtermcap does not look like sound logic either.

The "ac_cv_have_readline" check isn't present in trunk. I'll close this
unless someone voices opposition.

I don't have a Solaris box to test at the moment, but I believe the
following commit fixed this issue:

r66283 | gregory.p.smith | 2008-09-07 01:15:18 -0400 (Sun, 07 Sep
2008) | 5 lines

- Issue #1204: The configure script now tests for additional libraries
  that may be required when linking against readline.  This fixes issues
  with x86_64 builds on some platforms (at least a few Linux flavors as
  well as OpenBSD/amd64).


If it is the case, this issue should be closed as a duplicate of #1204.

Hmm why you dont use LDFLAGS ?
It is well documented what to expect during configuration and build phase.
