Blog – Running mozilla's McCoy on gentoo

McCoy is a utility from mozilla to sign update.rdfs of firefox/thunderbird addons, when you host the update.rdf yourself. You can download it from the McCoy-Site.
On my current gentoo-system McCoy wasn't running out of the box. It failed to start printing the error message:

$ ./mccoy
Couldn't load XPCOM.

The fix for me was to install the libpng12 library. On my system only the newer libraries libpng14 and libpng15 were installed. For installing libpng12 in a slot you have to run this as root:

$ emerge =media-libs/libpng-1.2.49 -av --oneshot

Note: see my next blogpost for better instructions
