pthread-changes from 1.6 to 1.7?

[Thomas Schlesinger]

Hi,

I don't know, if you've already seen it, so I post it here, too:

The pkgsrc-package lang/ruby18-base doesn't build on 1.7. The build breaks 
with this error message:

Takahiro Kambe has tried it on 1.6 and was able to build it. It seems, 
something has changed in DragonFlyBSD from 1.6 to 1.7, that prevents building 
this package. I don't know, if more packages are  affected.
