Is it possible to easily add gd libraries with libpng and libjpg after you have already compiled and installed php? I've followed the instructions under docs and compiled and installed, but now have decided I want to add the gd

I really don't know for sure. I think you need to recompile ;-(

sorry...

OK, I did recomplile and that worked. Seems like having to recompile every time there is an update or to add a library is a lot of work. I'm glad I'm not a sys admin.
