Non-standard install locations are problematic for compiled gems (like
sqlite-ruby). If you installed by hand, you could easily specify the
necessary "--with-sqlite-lib" and "--with-sqlite-include" parameters
to the install script, but with gems..

Chad, Jim, et. al.: is there a way (or could there be a way) to allow
the gem command to take optional parameters that get passed through
directly to the extconf.rb script?
