I've tried to install a few gems and have installed gruff,color-tools,hoe,image_science,midilib,pdf-writer,progressbar,rake,rubyforge without problems. I tried to install scrubyt and it failed with error reported similar to below. I subsequently tried to install hpricot and mechanize by themselves and these failed also, as below: ---- G5-QUAD:~ vangelon$ sudo gem install hpricot Select which gem to install for your platform (powerpc-darwin8.0) 1. hpricot 0.5 (ruby) 2. hpricot 0.5 (mswin32) 3. hpricot 0.4 (mswin32) 4. hpricot 0.4 (ruby) 5.
