pari: llvm-gcc compiles it incorrectly

Description (last modified by ryandesign (Ryan Carsten Schmidt))
the package pari is broken under OS/X Lion
This can be seen with the following (incorrect) calculation
gp> bezout(13,17) %1 = [1, -1, 4]
This is due to a bug in OSX Lion gcc compiler, and until Apple fixes it the pari package has to be build from source with gnu gcc instead of Lion gcc.

| Summary: | pari: clang compiles it incorrectly → pari: llvm-gcc compiles it incorrectly |
When built with clang I get:
? bezout(13,17) %1 = [4, -3, 1]
which appears to be correct according to the documentation of what bezout is meant to do.
Upstream bug report only mentions llvm-gcc: http://pari.math.u-bordeaux.fr/cgi-bin/bugreport.cgi?bug=1252
Therefore I have simply blacklisted llvm-gcc-4.2 for this port in r95549.

There is no "Lion GCC compiler". GCC is part of Xcode, not Lion, and as of Xcode 4.2, there is no GCC in Xcode. Furthermore, MacPorts does not use GCC to compile anything as of Xcode 4: in Xcode 4.0 and 4.1 MacPorts uses llvm-gcc-4.2, while with Xcode 4.2 and up, MacPorts uses clang. What version of Xcode do you have?
