Do you have a multithreaded apache1.3 ? It's very important to compile it as multithreaded and link pthread ! For the apr issues - I still think that apr should be treated as a general-purpose library, and we shouldn't have more than one varaiant in the system. Probably some APR expert could clarify this - but my opinion is that on linux the right place for apr is /usr/lib/libapr.so.0.9.2 and /usr/include/apr. And I think Apache2.0 RPM should just depend on libapr.rpm, and same for mod_jk2.rpm It's just too confusing to have 2 variants of the same library, and it should be a portability library that can be used outside apache - without apache having a special copy.
