libjpeg-turbo won't build in the +universal variant. The relevant config.log is attached.

I'm unable to reproduce this problem on Mavericks.

I see the problem on Mavericks, also affects mozjpeg (a libjpeg-turbo fork).

[raimue (Rainer Müller)]

I think the problem is the --host argument to configure, we can't use ${build_arch} there to pass different build flags as the Portfile is only parsed once but needs to be different per architecture. I don't know muniversal very well, but I think this would be the fix:

libjpeg-turbo fixed in r136594. mozjpeg was fixed in r119203.
