Hi Ken,
I loaded in 3.10 build 7159, from universes, almost without problems... 
and I said "almost" because I had to load the package before any 
other... otherwise, it hangs... and maybe there is something else wrong 
later, but for now, everything work well (right now I'm using just 
FreeType, but I will load more libraries next weeks)

Cheers,
Esteban
