Ezra, I found this cap plugin you posted to be extremely useful, ccing
Capistrano list, where I know you've posted about it too. I have a
patch, adding the options as a params hash for readability. My
cursory googling..err..searching could not reveal where this
capistrano "Gem" plugin resides.
main difference is this method:
def install(packages, source=nil, version=nil)
is now:
def install(packages, options={})
so you can do:
gem.select 'mysql', :version => '2.7', :platform => 'ruby',
:extra_params => '-- --with-mysql-config'
or:
gem.select 'mongrel', :version => '0.3.13.4'
Here's the diff, (email formatting is horrible), or point me to an svn
for latest to build a patch
$ diff cap_gem_plugin.rb cap_gem_plugin_cbq.rb
