First, thanks for your hints. AFAICT, none of the 150 most popular gems use GNU make features; there's just that side-effect of GNU make's idea of CXX. This is a little less straightforward than I might have expected. How should we document it for the OpenSolaris Web Stack? "The installation of Ruby native extensions requires the SUNWgcc package. gem is preconfigured to use gcc for C language extensions. Set the CXX environment variable to /usr/sfw/bin/g++ when installing C++ language extensions, such as eventmachine and thin. Example: # CXX=/usr/sfw/bin/g++ gem install eventmachine --/-- When this issue was encountered previously, was it considered more proper to 1) install SUNWgmake and adjust the path 2) set CXX 3) make rbconfig work out of the box (I'm not getting a read on how you think it should work.)
