Building Python bindings

From: Aaron Bingham <abingham_at_alumni.sfu.ca>

I am having troubling building the SWIG Python bindings. I am running
on Debian Woody, and have installed Python-2.3.5, httpd-2.0.53,
SWIG-1.3.21, and subversion-1.1.3 from source using the Graft package
manager. Apache and the Subversion module for Apache work flawlessly,
but my build of the SWIG Python bindings is still broken.

SWIG was configured like this:

./configure --prefix=/pkgs/SWIG-1.3.21 --with-python=/usr/local/bin/python

make; make install did not install libswigpy.so, so I tried following
the instructions at http://wiki.bwerp.net/Subversion and ran the
following commands:

echo '%module swigrun' > swigrun.i
swig -runtime -python swigrun.i
gcc -I/usr/local/include/python2.3 -fpic -c swigrun_wrap.c
gcc -shared swigrun_wrap.o -o libswigpy.so
install -o root -g root -m 755 libswigpy.so /pkgs/SWIG-1.3.21/lib

I then ran graft -i SWIG-1.3.21 to make the package available to
other software.

Subversion was configured like this:

./configure --prefix=/pkgs/subversion-1.1.3 \
    --with-apr=/usr/local/bin/apr-config \
    --with-apr-util=/usr/local/bin/apu-config --with-apxs \

After make and make install and graft -i, I ran make swig-py and make
install-swig-py, and graft -i once more.

Now, when I try to use the svn module, I get results as follows:

bingham@213-203-244-183:~/work/svn$ python

>>> import svn
>>> from svn import fs

  File "/pkgs/subversion-1.1.3/lib/svn-python/libsvn/fs.py", line 5, in ?
    import _fs
ImportError: libswigpy.so: cannot open shared object file: No such file or directory

LDD gives the following output for _fs.so:

        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaaa000)

This despite a symlink libswigpy.so being present in /usr/local/lib
and /usr/local/lib being present in /etc/ld.so.conf. Other libraries
in /usr/local/lib seem to be found without trouble.

Any ideas?
