rspec 1 using rspec and rspec 2 using rspec2. Additionally, add
support for ruby and testrb, calling the appropriate binary for the
ruby implementation.
Start checking sanity of MODRUBY_REGRESS entry, using a fatal error
if it is defined and doesn't contain a recognized word.
Instead of RAKE_REGRESS_TARGET and RSPEC_REGRESS_TARGET, just use
MODRUBY_REGRESS_TARGET for all cases. On ruby 1.9, modifying the
environment to always look in the current directory for libraries
(the ruby 1.8 behavior), since many ports depend on that for regress.
Allow ports to set their own regress environment and current directory
using MODRUBY_REGRESS_ENV and MODRUBY_REGRESS_DIR.
