i don't think the problem is ports related. imo the problems are being caused by the linuxulator not being able to emulate the linux kernel 2.6 100%. if that's the case there's nothing we can do except wait until the linuxulator get's fixed.
here's a problem report: http://www.freebsd.org/cgi/query-pr.cgi?pr=133144
a thread on EMULATION: http://lists.freebsd.org/pipermail/f...il/005823.html
and one on CURRENT: http://lists.freebsd.org/pipermail/f...ch/004563.html
so far nobody seems to be taking care of the problem however.
if anybody is able to run linux games using the linuxulator 2.6, please tell us how you managed to do so.
