php_svn.dll with Apache/2.0.63

hi y'all,
is there a known issue with php_svn.dll (5.2.1.1) on Apache/2.0.63 (windows
xp sp 2 - 32bit)? i am  pretty sure i did configure it well, but for some
reason apache fails to use this extension. the svn extension is usable from
the cli but not via apache. any pointers will be of great help.

Thanks,
Vedanta
