 Trying to install py27-crypto fails. The last posting on this site I can
 see about py27-crypto is 21 months old...

 Log file points to a build error in clang.  (error copied below)

 XCode 4.4 on 10.8 (setting up a new machine) and a new download/install of
 macports.

 {{{
 :info:build /usr/bin/clang -bundle -undefined dynamic_lookup
 -L/opt/local/lib -arch x86_64 -arch x86_64
 build/temp.macosx-10.8-x86_64-2.7/src/_fastmath.o -lgmp -o
 build/lib.macosx-10.8-x86_64-2.7/Crypto/PublicKey/_fastmath.so
 :info:build ld: illegal text-relocation to ___gmp_binvert_limb_table in
 /usr/local/lib/libgmp.a(mp_minv_tab.o) from ___gmpn_divexact_1 in
 /usr/local/lib/libgmp.a(dive_1.o) for architecture x86_64
 :info:build clang: error: linker command failed with exit code 1 (use -v
 to see invocation)
 :info:build error: command '/usr/bin/clang' failed with exit status 1
 :
 }}}

 I have tried also forcing to use gcc (4.2), apple-gcc-4.2, and gcc-llvm
 (as listed on the Problem Hotlist page) to no avail.

 Thanks

Comment:

 Because of how the Python build process works, changing the compiler for
 Python modules has no effect. Modules will always build using the same
 compiler that was used to compile Python itself.

 The error message points to the file /usr/local/lib/libgmp.a, which
 appears to be interfering with the build. We do not support using MacPorts
 while there is software installed in /usr/local precisely because of the
 likelihood of interference like this. Please remove that file (and
 anything else you might have in /usr/local), clean the port, and try
 again.
