 Hi,

 I'm trying to install the port for graph-tool. The following error occurs
 when I run 'port install graph-tool':

 {{{
 Error: Cannot install py27-graph-tool for the arch(s) 'i386 x86_64'
 because
 Error: its dependency py27-scipy does not build for the required arch(s)
 by default
 Error: and does not have a universal variant.
 Error: Unable to execute port: architecture mismatch
 }}}

 I'd think that scipy would have a universal variant, but then again, I'm
 new to Mac (from the linux world), so I'm not quite sure how this
 universal variant stuff works. I'm running Lion, 10.7.2.

 Thanks, [[br]]

Comment:

 Please put the correct port name in the Summary and in the Port field, and
 remember to Cc the maintainer(s) of that port.

 You can run "`port variants py27-scipy`" to see that it does not have a
 universal variant. It has gcc variants, which also explains why it doesn't
 have a universal variant: the MacPorts gcc compilers those gcc variants
 use cannot produce multi-architecture files.

 So, sorry, you cannot install py27-graph-tool universal, because its
 dependencies cannot be universal. py-graph-tool should disable its
 universal variant.
