The gcm-picker command is completely non-functional with calibration devices supported by Argyll CMS. The problem is that Gentoo didn't patch it for the Gentoo-specific renaming of Argyll executables. Reproducible: Always Steps to Reproduce: 1. Connect a colorimeter such as ColorMunki Display 2. Run gcm-picker from the terminal 3. Press the Measure button Actual Results: (gcm-picker:4089): Gcm-WARNING **: failed to get sample: failed to spawn /usr/bin/spotread Expected Results: No such error There is indeed no /usr/bin/spotread on Gentoo systems. There is /usr/bin/argyll-spotread.
