I would like to notice that now, on gentoo (sabayon-32bits-5.3), to install
BRP_PACU I had to create a link in /usr/lib/pkgconfig :
ln -s /usr/lib/pkgconfig/libpng14.pc /usr/lib/pkgconfig/libpng12.pc
to see make working.
One other thing : how to launch BRP_PACU straight from my menu without
having to go in the folder with a terminal ?
