Another possible solution...
Are you getting: TracError: Unsupported version control system
"svn" ???
Or how about: ImportError: /usr/local/lib/libsvn_ra_dav-1.so.0:
undefined symbol: gss_delete_sec_context ?
If you are getting the first error mentioned, go to the command prompt
and type: python -c 'from svn import fs'
Well, it took me several hours of pain to figure out a solution. So
I've decided to reply to every thread in the Trac mailing list so that
others will be sure to stumble upon a (possible) answer. I installed
Trac 0.10.3 on RHEL4.
Here's the site that cured my pain: http://www.liucougar.net/blog/
archives/53/
Basically, recompile subversion but edit the Makefile so that neon
will explicitly link against gssapi lib:
vi subversion-1.4.2/Makefile
old: SVN_APR_LIBS = .../subversion-1.4.2/apr/libapr-0.la -lrt -lm -
lcrypt -lnsl -lpthread -ldl
new: SVN_APR_LIBS = .../subversion-1.4.2/apr/libapr-0.la -lrt -lm -
lcrypt -lnsl -lpthread -ldl -lgssapi
then compile + install again.
You can always not compile neon, but don't you want to browse your
code online? ;-)
Btw, if you apply the above solution but get the new error:
ImportError: libsvn_swig_py-1.so.0: cannot open shared object file: No
such file or directory
Then just reboot your box. Something is cached and needs to be
restarted.

It could also mean that Neon (a SVN dependancy) isn't built correctly. My recommendation. Find your neon install ( i can almost guarantee it's inside the src folder for your svn install) and rename the folder. Go into that folder and build new using the shared and static enables, also make sure that neon is built against ssl. This will prevent svn from building neon when it gets built. Then rebuild your svn by first doing a make clean and make clean-swig-py. run ./configure (with any flags you want) do a make && make swig-py. then do a make install && make install-swig-py. That should help get you on your way. <BR>
