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 As part of overall upgrade to outdated ports (see mesa-upgrade.log), i.e.

sudo -E port upgrade outdated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 Problem Hotline 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).
