Thanks. For future reference, we prefer to receive a unified diff instead of a complete new portfile; this lets us more easily evaluate your proposed changes. Use the keyword "haspatch" if you're providing a patch, and the keyword "maintainer" if you're the maintainer of the port.

Committed in r114461. I also added a patch to fix three problems:

• The configure script was clearing CFLAGS, which led to universal builds failing (#28924).
• The configure script was detecting and using dependencies from Fink if installed, which we never want to happen.
• The configure script was using echo -ne "\n" to print a newline in the summary, however echo -n is not portable and on POSIX-compliant systems including Mac OS X 10.5 and later, this does not have the desired effect, resulting instead in the literal characters "-ne" being printed. The general fix is to use printf in place of echo -n but in this case for simply printing a newline one can just run echo with no arguments.
