Metasploit on FreeBSD (and a couple of other questions)

[jimbo at abs.net (Jim)]

1. Does anyone have msfgui working on i386 FreeBSD?  The Ruby 
installation is driving my crazy because of the version specific 
requirements and the missing zlib bug in 1.8.6.  Mfsconsole works fine, 
but I'd like to use the gui sometimes.  Any tips or pointers?  (Or if 
you have a URL for a copy of i386/FreeBSD zlib around, I'd appreciate it.

2. I'd like to explore writing exploits for Metasploit.  Google gives 
about a million results.  Are there any really good, comprehensive sites 
for learning about this?

3. After looking at SuSe, Ubuntu, Fedora, and FreeBSD for my pen-testing 
platform of choice I settled on FreeBSD mainly because wireless support 
seemed to be the most mature.  Was that a mistake?  I'm not trying to 
start a religious war, but is there an OS that is generally regarded as 
the best for running the tools we use that often need to do strange 
things?  (Metasploit, dsniff, aircrack, etc etc etc.)

Thanks for any input.
