Trying to "pip install reportlab==3.0" and I get a crazy long error with include header <string.h>

Question

I am trying to pip install reportlab==3.0 and I am not having any luck getting past this error. Can someone tell me what I am missing? The latest version of reportlab installs okay but I can't use that.

I have tried easy_install and all versions. It seems that < 3.0 I will get the same error but with > 3.0 I am okay.

I have also made sure my headers are linked. It looks like towards the end there is even some javascript errors? This has had me stumped
