Which version of tor are you using?
We need emerge --info.

Disable use of internal libevent parts

Diego, you could do me a big favour:
a) you tell me how I check for the internal copy
b) you try attached patch
Comment 5 Christian Faulhammer (RETIRED) gentoo-dev 2009-01-30 08:45:30 UTC
I reported the problem upstream (see URL).
Comment 6 Christian Faulhammer (RETIRED) gentoo-dev 2009-01-30 21:20:42 UTC
Diego, no need to test it...upstream will introduce a configure switch to use the system libevent.
Comment 7 Christian Faulhammer (RETIRED) gentoo-dev 2009-02-05 00:36:39 UTC
I know consider this as fixed.  First my solution including my rationale:

net-misc/tor has USE=bundledlibevent turned on by default (EAPI=1), so people will still get the current bundling out of the box.  If that USE flag is disabled a patch is applied that compiles tor with the system's libevent.  The reason is that tor's upstream incorporated some security related fixes into the tor version of libevent that are not released with the official libevent yet.  This looks like the best possible solution until upstream provides the autoconf switch to move away from the bundled version.  As soon as the enhanced libevent version makes it into Portage, the USE flag will leave.
