Hi, I just recently did an emerge on Gentoo and installed the Gimp 2.2, but my problem is that some extensions, specifically png and jpeg, don't seem to be supported. I can't save a file as these types, and when I try ro open one I get:

"Opening 'file.png' failed:
Unknown file type."

I know I have libpng and jpeg support in. Is there something I need to do to make these work? Thanks in advance.
