Yes, it's a way to do it, also you can create a file with the options as "/etc/portage/env/options" and then simlink to "/etc/portage/env/category/package"...
This way you will always emerge this package with the settings declared in the environment dir, it's also usefull so made some optimizations over especific packages without affect the rest of the system, or when a package needs especial values in environment variables as LC_ALL, i.e. ghc-6.8... 2008/5/25 dhk <[EMAIL PROTECTED]>: > I did the build the non-persistent way and ran my program with the > debugger.
