Blender won't start from command line Ubuntu 11.10...

Hi Y’all,

I’m running blender 2.62 on Ubuntu 11.10 unpacked from site and that runs fine…but I installed blender from the PPA also, but when I try to start it (or find it for that matter) I get the message: “illegal instruction”. And where are these files installed? I’m doing this on an old Toshiba Satellite Pro 4600. My main computer is a 4 i5 processor with 8gb memory…and the PPA works fine there.

I’ve tried going to the /usr/bin directory and typing in: blender, ./blender, or .blender no go…any ideas what I should do?
