SuiteSparse: update to 4.0.0

[zan@…]

Update SuiteSparse to version 4.0.0. Related ports metis (updated) and scipy (patched).

Solves ticket #32788.

Tested with Apple gcc-4.2, llvm-gcc-4.2, clang, and Macports gcc-4.5 on Snow Leopard 10.6.8, 32/64 bit.

that should have been type: update, not type: new defect.

The patch fails to apply for me, also it contains whitespace changes so it's difficult to see what's changed. Can you attach a series of patches that separates whitespace changes from functional changes?

Unified diff of Portfile

[zan@…]

Attached a new diff file. Minimized whitespace changes and stayed closer to style of previous version. Also links to libmetis.dylib instead of libmetis.a (since metis version 5.0.2_1). Removed a few unnecessary changes.

Thanks, that almost applies cleanly although there are still a few issues (e.g. you removed epoch which is always bad), I've attached a clean patch that builds for me. Can you confirm that this is correct? If so I'll push this.

I thought epoch was only needed for the forced downgrade from 3.7.0 back to 3.4.0, months ago. It needs to stay?

Patch works for me.

Once epoch has been set it can never be removed or decreased.

This failed to build on the ​buildbot. It built on my Lion machine, but not on the Snow Leopard buildbot. As you provided this patch, any ideas?

[zan@…]

SPQR module uses g++, therefore the dylib needs to be linked using g++. Patch attached.
