[GEM-dev] [ pd-gem-Bugs-1771966 ] texturing movies pegs CPU using fglrx/ATI Radeon X1x00

Thu Mar 6 11:02:28 CET 2008

yo, i would like to do so (as soon as Gem will be included), but
probably i won't be able too, becaue i am still running ubuntu dapper
and won't be able to fulfill the dependencies of pd-extended for current
debian/ubuntu. 

which autobuild would you recommend?
