MetaSploit bundled ancient metasm version conflict with system version fix

[GoogleCodeExporter]

As noted by ZC,
emerge -C metasm will correct the problem

I've tested it and it works.

AlphaZero Release.

I found a quick workaround:
export RUBYLIB=$RUBYLIB:/usr/lib/metasploit/lib/metasm

an another (risky) way of fixing the issue is to unbundle the metasm and use 
the external latest trunk. That might break and fix things in the same time and 
requires thorough testing. Please test the latest trunk:

Add the fix from comment 1 to files dir and "newenvd metasploit-ruby-hack" or 
whatever.  comment number 2 is not possible as metasploit uses (and I quote) 
"an ancient obsolete version of metasm"

Guys, I've just pushed an another attempt to fix in 
https://code.google.com/p/pentoo/source/detail?r=3222#.
This time we use the global MSF_LOCAL_LIB="/usr/lib/metasploit/lib/metasm" 
variable. Works for me (tm). Please test it on your side and close the issue.

You need to fix your symlink. I expect it always be
/usr/lib/metasploit
