library not found for -lbundle1.o
I'll begin by saying that I believe the problem with this could be unique to my machine.  I'm running OSX Lion on a MacBookPro.

Attempting to easy_install pandas I get:

```
gcc: pandas/src/tseries.c

gcc -bundle -undefined dynamic_lookup -g -arch i386 build/temp.macosx-10.5-i386-2.7/pandas/src/tseries.o -o build/lib.macosx-10.5-i386-2.7/pandas/_tseries.so

ld: library not found for -lbundle1.o
```

A little searching led me to clone the git repo and make the following patch to setup.py:

```

~/git/pandas(master) $ git diff
diff --git a/setup.py b/setup.py

               sparse_ext]

```

...which gave me a good build.

I can try an install on my iMac at the office tomorrow to see if it's just a problem with my libraries/paths on this machine, but I wanted to document this here before I lost it.

BTW, I'm installing it into a recent (latest?) Enthought Python Distribution:
Python 2.7.2 |EPD 7.1-1 (32-bit)| (default, Jul  3 2011, 15:40:35)

Best,

Travis
