>Description:
If devel/yasm older than 0.6 is installed, devel/SDL from pkgsrc 2007Q1 fails on the MMX assembly:

>How-To-Repeat:
As stated above, build devel/SDL with a version of devel/yasm before 0.6.
>Fix:
I think you just have to inhibit detection of yasm if it's an old version, but I'm not sure how to do that.  I worked around the problem by uninstalling yasm entirely and letting SDL build with nasm.
