Get pycrypto to build on FreeBSD

[kcrisman]

Stephen Montgomery-Smith reports:

OK, I started working on building sage.  So far I can get all the spkg's to build except:

gap-4.4.12.p6
pycrypto-2.1.0
singular-3-1-3-3.p3
maxima-5.23.2.p3
sage-4.8

The build problem with pycrypto-2.1.0 and singular-3-1-3-3.p3 are easy to fix.  

The patch is apparently

Use git branch.

I can confirm that this ticket is still required for building sage with FreeBSD. It should be harmless to all other OS builds.

Add a new file patches/src.libtom.tomcrypt_pk.h (you will have to add the patches directory as well)

I erased this comment and the following comment as they were wrong.

[kcrisman]

All that's needed here is a new spkg with an spkg-install that checks whether the patch was applied correctly.

[jpflori]

The fix is still needed and let pycrypto build on FreeBSD 9.0 x86. I'll package a spkg this weekend.

[jpflori]

The week-end was kind of long. Uploaded a simple spkg.

Follow up ticket to upgrade pycrypto at #14854. Note the patch should still be needed. The patched file did not change. Time for an upstream bug report I guess.

[jpflori]

Spkg diff, for review only.

I've made a git branch and reported upstream at:

• ​https://bugs.launchpad.net/pycrypto/+bug/1264130

[git]

Branch pushed to git repo; I updated commit sha1. New commits:

Let PyCrypto build on FreeBSD.
