Compile Failure Ruby 2.1.0

[gordonk]

Thanks for a great project. Has made building a ruby tile server very simple.

Keeping on the bleeding edge I tried to build a ruby 2.0.0 ruby_mapnik application to ruby 2.1.0

Got:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Followed by page after page of:

/Users/gordon/.rbenv/versions/2.1.0/bin/ruby extconf.rb

/Users/gordon/.rbenv/versions/2.1.0/lib/ruby/2.1.0/rubygems/ext/builder.rb:89:in `run': ERROR: Failed to build gem native extension. (Gem::Ext::BuildError)

Then

sh: fork: Resource temporarily unavailable
/Users/gordon/.rbenv/versions/2.1.0/lib/ruby/2.1.0/rubygems/ext/builder.rb:89:in `run': ERROR: Failed to build gem native extension. (Gem::Ext::BuildError)

/Users/gordon/.rbenv/versions/2.1.0/bin/ruby extconf.rb

extconf failed, exit code 128

Then page after page of:

It appears to be unhappy about cairo but its not cairo itself, that installs fine as a Gem.

Sorry I can't give you anymore information. The error message is a bit sparse.
