Just tried blender-2.49a, and got a hang.

$ blender -d
Blender 2.49 (sub 2) Build
argv[0] = blender
argv[1] = -d
Compiled with Python version 2.6.2.
Checking for installed Python... got it!

If I strace I see...

read(3, 0xfffffffc210, 32)              = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=3, events=POLLIN}], 1, -1

[Comment 2 Greg Trigg 2010-07-19 10:24:31 UTC]

I notice you're using gcc-4.3.2 on this.  ppc64 doesn't like 4.3 I've discovered.  You may want to switch back to 4.2 or use ~ppc64 keyword to get 4.4.

you are mistaken... gcc-4.4.3-r2 is stable on ppc64 now

Tried gcc-4.4.3-r3, but it didn't work just as before.

Please try again with blender-2.63a and reopen if it's still an issue.
Thanks,
