I download sage-6.5-x86_64-Darwin-OSX_10.7_x86_64-app.dmg. Everything seemed fine, but I tried to using ./sage pip install pandas and got the following error:
error: command 'gcc' failed with exit status 1

I also tried ./sage --sh followed by pip install pandas and received the same error.
A somewhat similar question is listed here: http://ask.sagemath.org/question/10978/how-to-upgrade-a-python-package-with-pip/
I used what was listed there, but have been unable to figure out how to solve this issue.
