When compiling photomolo jpegint.h seems to be lacking.
It's supposes to be there because it's included by jpeglib.h, and I found it in the jpeg-7 tarball
So I presume jpegint.h is not installed by the ebuild.
You may consider this a duplicate (in a way) of bug 282765.
Short of it - NOTABUG.
And if that photomolo is in the tree (doesn't seem that way),
it will be probably treated as an upstream bug.
* Applications using the library should not include jpegint.h, but may wish
* to include jerror.h.
It might get included by jpeglib.h if the external program sets #define JPEG_INTERNALS, this is wrong...
Instead it should include jerror.h by itself if required.
Found photomolo from Freshmeat, with this patch it will build without jpegint.h.
