Ruby gem quirk on Windoze

Considering gem spec file name “GothicInnovation.gemspec”:

“gem build gothicinnovation.gemspec” executes perfectly.
“gem install gothicinnovation” pukes.
“gem install GothicInnovation” executes perfectly.

“gem build” is not case sensitive, where as “gem install” is. Quirky,
but so is Windoze.
