After emerging acroread-7.0.5, acroread seems to take very long (>1 min) to load. Deleting ~/.adobe/Acrobat/7.0/Cache/UnixFnt07.lst temporarily solves the problem, but that file keeps getting generated. acroread-7.0.1.1 doesn't have this problem. Some other people are experiencing the same problem: http://forums.gentoo.org/viewtopic-t-420754-highlight-acroread.html
I don't see what we could fix here. Complain to Adobe, please.
for me it helped to create an empty ~/.adobe/Acrobat/7.0/Cache/UnixFnt07.lst file
