nmap fails to build

[johnmusbach1@…]

MacBook Intel Core 2 Duo 2.16Ghz with 2GB RAM running Mac OS X 10.6.1. Tried to install nmap but it fails:

Error: The following dependencies failed to build: pcre Error: Status 1 encountered during processing.

Tried to fix dependency issues but that failed too:

So kind of stuck here.
