Ow. Okay, getting back to the more obvious solution, to link the two .so's
together, let me document the exact details of the workaround for the
benefit of readers:
Adding the .la file from the rlm_sql/.libs/ directory to that ghastly
libtool invocation, seems to work for me:
% cd ~/freeradius-2.0.3/src/modules/rlm_sqlippool
% /usr/bin/libtool --mode=link gcc -release 2.0.3 -module -export-dynamic -o
rlm_sqlippool.la -rpath /usr/lib/freeradius rlm_sqlippool.lo rlm_sqlippool.c
/home/joy/freeradius-2.0.3/src/lib/libfreeradius-radius.la
/home/joy/freeradius-2.0.3/src/modules/rlm_sql/rlm_sql.la -lnsl -lresolv
-lpthread

And freeradius runs with this /usr/lib/freeradius/rlm_sqlippool-2.0.3.so
replaced.
Paul Hampson wrote earlier that he had problems plugging this into the
Makefile system, because he added:
RLM_LIBS = $(topdir)/src/modules/lib/rlm_sql.la
Instead of that, I had added:
RLM_LIBS = $(top_builddir)/src/modules/rlm_sql/.libs/rlm_sql.la
But actually both versions seemed to get it to link for me, my libtool
didn't have a problem finding src/modules/lib/.libs/rlm_sql.so
and giving that to gcc. It's 1.5.22, from etch, which might be relevant.
