This appears to be SWIG bug 1481958.

http://sourceforge.net/tracker/index.php?func=detail&aid=1481958&group_id=1645&atid=101645

I'd be grateful if people could try the following:

   svn checkout 
http://svn.collab.net/repos/svn/branches/perl-bindings-improvements

   cd perl-bindings-improvements
   ./autogen.sh
   ./configure \
     --enable-maintainer-mode \
     --enable-debug \
     --without-neon \
     --without-berkeley-db
   gmake MAKE=gmake
   gmake MAKE=gmae swig-pl

(the MAKE=gmake bit is necessary on platforms where GNU make is not 
"make", if that's not the case on your platform then just "make; make 
swig-pl" should suffice).

Then

   cd subversion/bindings/swig/perl/native
   perl Makefile.PL
   make
   perl -Iblib/arch -Iblib/lib t/client/list.t

I expect that on 32 bit platforms that test will fail, and on 64 bit 
platforms it will succeed.  I've only got a 64 bit platform available at 
the moment, and I want to make sure the problem is definitely there on 
32 bit platforms before I work on a fix.

Many thanks,

N

(That was run for me when I did the 'make swig-pl'.  I assume that's
normal).

Works fine for me on a 32-bit Pentium 3 running Slackware:
(SWIG 1.3.29, Perl 5.8.8, APR 1.2.7).

I did have to apply a patch to get the Perl bindings to build at all, so
it's possible that may have worked around the problem:

The build problem I had was that it's not possible for me to #include
the APR headers unless I include the flags from 'apr-config --cppflags',
because otherwise apr_off_t is typedef'd to off64_t, and the latter
isn't defined.

Including the relevant flags from apr-config (in my case,
-D_LARGEFILE64_SOURCE) fixes the problem.  The attached patch replaces
the default set of MakeMaker CCFLAGS with the set defined by 'apr-config
--cpp-flags --cflags'.  I have no idea whether it's correct generally,
but I can't build the bindings otherwise.
