Unless you’re using RI or rdoc, you can install the gem with --no-ri. Next version of the gem will “solve” that. ---

Since people are talking about the mysql gem, I thought I’d ask how you can build it under MinGW. I can’t seem to make any combination of extconf switches work. I have the standard Windows mysql-5.1.42-win32 installed in /usr/local/mysql. Do I need some MinGW-specific version? (I’ve tried compiling it from source with MSYS/MinGW and also Cygwin, with no success.)
