mesa @10.4.4_2 build failure

[jane.r.allison@…]

mesa build fails in following circumstances:

1. As part of overall upgrade to outdated ports (see mesa-upgrade.log), i.e.

sudo -E port upgrade outdated

2. When explicitly (re)installing mesa using default settings (see mesa-default.log), i.e.

port -E sudo install mesa

3. When explicitly (re)installing mesa using llvm-gcc-4.2 as recommended on the ProblemHotlist page (see mesa-llvm-gcc-4.2.log), i.e.

sudo -E port install mesa configure.compiler=llvm-gcc-4.2

4. When attempting to install texlive, which in turn installs pymol, which requires mesa (see mesa-pymol.log), i.e.

sudo -E port install texlive +full -medium

To make matters more confusing, different errors are encountered each time. Machine specs are: OS 10.7.5, Xcode version 4.6.1 (but am using ports via the command line so not sure if this is relevant).

Regarding (3), I've removed the portion of the ProblemHotlist that suggested trying llvm-gcc-4.2 and apple-gcc-4.2. That section dated from several years ago, when clang first became the default compiler. At that time, many ports failed to build with clang; by now, clang is more mature, and ports have been updated to work with clang, so the suggestion to try another compiler is no longer generally useful.
