Comment 2 dkaris 2008-10-17 21:56:40 UTC 
My ruby\bin directory contained a "gem.rb" but did not contain a "gem" or "gem.bat" file.  I created "gem" as a copy of
"gem.rb" and "gem.bat" as 

@ECHO OFF
@"ruby.exe" "%~dpn0" %*

This resolved the problem.

Note also, that before this change, the "Ruby Platforms" dialog showed my Gem Tool as "null (1.2.0)"; after this change
it showed "c:\ruby\bin\gem (1.2.0)"

This might get fixed in 6.5 RC1 (http://www.netbeans.org/community/releases/65/). But I've committed several robustness
fixes in Changeset #25ee45dfeb59). Thus setting TM to 7.0.

Commit log:
Introducing RubyPlatformValidator, relaxing RubyPlatform, more robustness, less copy-paste.
