Stop. That missed feature doesn't relate to this problem at all.

I still don't understand why the following is not a cycle.

   0 p5-version>bmake show-var VARNAME=BUILD_DEPENDS
   {perl>=5.10,p5-Module-Build>=0.2608nb1}:../../devel/p5-Module-Build

   0 p5-version>cd ../p5-Module-Build
   0 p5-Module-Build>bmake show-var VARNAME=DEPENDS
   ...
   p5-version>=0.74:../../devel/p5-version
   ...

   0 p5-Module-Build>

Also I don't see a documentation for

    {perl,completely-different-pkg}:../../devel/completely-different-pkg

syntax in pkgsrc Guide section 19.1.7 and pkg_info(1).

According to the documentation above {} braces should be expanded to

    perl:../../devel/completely-different-pkg
    completely-different-pkg:../../devel/completely-different-pkg

And there is no perl package in devel/completely-different-pkg.
I don't understand this. Any help?
