media-libs/jpeg-7 installs .so.7.0.0 so this causes some headacke for binary applications:
media-libs/jpeg-compat-6b will install libjpeg.so.62{,.0.0} for use with binary applications, let me know if there is a trouble with the package. This means you have change deps to || ( media-libs/jpeg-compat <=media-libs/jpeg-7 ) for example. Feel free to use suitable alternative syntaxes. Otherwise it just means a long @preserved-rebuild emerge. jpegint.h isn't installed anymore (private header), if this is causing trouble for you let me know about that too... Thanks, Samuli
