Bizarre swig-pl build problem

I'm trying to compile a reasonably fresh version of Subversion for a
Fedora Core 6 machine. My route to doing this has been to download the
Rpmforge SRPM for Red Hat Enterprise 5 and try to rebuild it.

I've now tried both 1.5.6 and 1.6.5, and both fail on a bizarre linkage
problem inside the Perl swig bindings. Seeing as the particular thing I
want from this build are the Perl bindings this is quite a problem.

The link problem manifests as below[1], I've wrapped the lines for
clarity. The issue is that no -L specifier is created for the
"subversion/bindings/perl/libsvn_swig_perl/.libs directory.

Now I can read from the subversion/bindings/swig/perl/native/Makefile.PL
file that "$swig_builddir/perl/libsvn_swig_perl/.libs" is indeed added
to the lists of paths. Equally this path ends up as a _comment_ about
the MakeMaker parameters in the generated Makefiles. However, the
EXTRALIBS and LDLOADLIBS don't end up with the path, for some reason.

What I've since found is that if I go into the failed build and re-run
"perl Makefile.PL", the Makefiles are generated correctly. What could be
  causing the path to disappear from the generated Makefiles!?

Yours questioningly,

John.
