I've been through the same exercise that you did today a few times over the last couple of years, but never on Solaris with WebStack. You're right, there's no reason to favour GNU make over Solaris Make, it's just that on Nevada/OpenSolaris it can be unpredictable given that there's 4 make commands on the system with two of them actually named 'make'. BTW: Thin only requires CXX to be set because it installs EventMachine, same difference to an end user though > > This is a little less straightforward than I might have expected.

That looks ok, I'd rather it was unnecessary to have to read docs just to install a gem but given what I'm going to say in response to your last question it may be the only solution.

Option 2) is preferred. Option 1) is a non-option really, it's too cumbersome to be useful, read docs, install package, set PATH. Option 3) Maybe it's just my personal prejudice. Given that under normal circumstances rbconfig.rb will always have the last say on the settings that are used to build a gem, if CXX is set there then it can't be overridden. If this was a Ruby specific variable then I'd be less concerned but maybe someone one day will want a Ruby app to pick up CXX as set in the user's environment. Raise a bug for it, I'll see if there's a way that it can be done that will satisfy my concerns without requiring the end user to google or otherwise refer to docs.
