Question about pkgsrc that I didn't see covered in the FAQ.

Does pkgsrc use any sort of lockfile mechanism to indicate that's
currently being built?  I imagine there is, to prevent recursive
dependencies from causing a loop.  In my example, I have an older slower
machine, and I want to start building two "meta"  packages at once before
I head out, but I imagine they share some basic dependencies (libraries -
I imagine GMOME will get involved).  In theory, they could both attempt to
build the same package dependency at once, causing problems, correct?
