* HOMEBREW\_DEBUG:
If set, instructs Homebrew to always assume `--debug` when running commands.
* HOMEBREW\_TEMP:
If set, instructs Homebrew to use `HOMEBREW_TEMP` as the temporary folder
for building packages. This may be needed if your system temp folder and
Homebrew Prefix are on different volumes, as OS X has trouble moving
symlinks across volumes when the target does not yet exist.
This issue typically occurs when using FileVault (or certain custom SSD
configurations.)
* HOMEBREW\_USE\_LLVM:
If set, instructs Homebrew to use the LLVM front-ends to the GCC compilers.
*NOTE*: Not all formulae will build correctly under LLVM.

Your Cellar and TMP folders are on different volumes.
Your Cellar and /tmp folders are on different volumes.
Putting your Cellar and TMP folders on different volumes causes problems
for brews that install symlinks, such as Git.
Please post the details of your setup to this existing issue, if the comments
there don't already capture them:
http://github.com/mxcl/homebrew/issues/issue/1238
A work-around is available in this branch:
http://github.com/adamv/homebrew/tree/temp
You should set the "HOMEBREW_TEMP" environmental variable to a suitable
folder on the same volume as your Cellar.
