Trac unable to work with Subversion

I have Collabnet Subversion 1.6.9, Trac 0.11.6, Python 2.6.1 from Sun's Webstack, Sunfreeware.com's swig 1.3.36 running on Solaris 10 5/09 SPARC.

I have these error code when open Trac page.

Please advice. Thanks.

the error message is complaining about the libsvn is build against some older version of python. try rebuild that library and instruction is here. (i am not on Solaris..., so i did not try it myself...)

The warning is ignorable.

Previously, I had a problem browsing the source on Trac.
After I reconfigured the subversion to run its webserver on Apache instead of svnserve, I am able to browse the source.

It's possible that viewvc must be installed to be able to browse the source through HTTP.
