Which version? Also, please don't link to external sources in problem
description, post the actual strace and other information here. And you
neglected to post emerge --info output as instructed to when filing the bug.

Could you please retest with ganglia-3.0.2 ?

[Comment 4 Nico Rittner 2006-01-24 03:55:39 UTC]

(In reply to comment #3)
No segfaults, forks and binds correctly.
Is it ready for production use ?, so i'll
put '~x86' into package.keywords for ganglia.

Reported fixed in 3.x
