Doing a emerge world, I ran across the problem of mjpegtools not proprely requiring the pango library. This is the latest version of this package as of this date. Reproducible: Always Steps to Reproduce: 1. emerge mjpegtools without having pango on your system. Actual Results: Compile broke complaining of missing header files. Expected Results: Properly compiled and installed :) I would paste, but I only have console access to the machine with no mouse. I'm sorry I can't provide any more information.
By 'latest' package you mean latest ~masked or latest stable? Can you give exact version number?
compiles here without pango
