Created attachment 120732 [details]
ebuild causing that backtrace

[Comment 2 Jan Kundrát (RETIRED) 2007-05-30 22:52:55 UTC]

Found the cause. If there's an extra space between use flag name and question mark in the DEPEND, it breaks.

[Comment 3 Zac Medico 2007-05-30 23:24:09 UTC]

Thanks, this is fixed in svn r6679.

[Comment 4 Zac Medico 2007-05-31 01:29:20 UTC]

This has been released in 2.1.2.9.
