When dev-lang/tk is installed with USE=threads, and USE=tk is set on dev-lang/ruby, ruby flat out refuses to emerge--even if threads is also set on ruby. Reproducible: Always Steps to Reproduce: 1. Run "USE=threads emerge tk" 2. Run "USE="threads tk" emerge ruby" Actual Results: When attempting to emerge ruby, emerge prints this: emerge: there are no ebuilds built with USE flags to satisfy "dev-lang/tk[threads=]". !!! One of the following packages is required to complete your request: - dev-lang/tk-8.5.8-r1 (Change USE: -threads) - dev-lang/ruby-1.8.7_p302 (Change USE: +threads) (dependency required by "dev-lang/ruby-1.8.7_p302" [ebuild]) (dependency required by "ruby" [argument]) Expected Results: Emerge should emerge tk with threads, then emerge ruby with threads and tk support.

One of the following packages is required to complete your request: > - dev-lang/tk-8.5.8-r1 (Change USE: -threads) > - dev-lang/ruby-1.8.7_p302 (Change USE: +threads) I don't see how this is a bug. The output tells you that you either need to set -threads on tk or +threads on ruby. That means you cannot do "USE=threads emerge tk ruby".
Of course, it is abit confusing. I may be wrong too after thinking about it more. =/
I figured out why this is failing. The threads flag is forced off on Mac OS X: [ebuild R ] dev-lang/ruby-1.8.7_p302 USE="berkdb gdbm ipv6 ncurses readline ssl tk -debug -doc -examples -libedit -rubytests -socks5 (-threads) -xemacs" 0 kB Notice the parentheses around the '-threads' USE flag. MacPorts seems to have a special variant for their Ruby port (that's on by default): ruby has the variants: ... [+]thread_hooks: apply Apple's thread_hooks patch Apparently, Apple has locally modified Ruby, and this "thread_hooks" patch is needed to make threading work on Mac OS X. I don't know if this will allow us to stop forcing USE=threads off for ruby, but it's worth a shot IMO.
I don't know where the mask comes from, but it feels like we indeed can apply MacPort's patch for USE=threads on OSX.
The patch that macports applies, is actually not (no longer?) applied by Apple. So I rather don't have it.
The threads mask is simply out-of-date. I removed the mask, that should fix this bug.
Closing. Thanks for fixing this!
