  You misread the documentation, see below.

: I think it means: it can depend either on X or Y, and building ../../A/Y

  Exactly.  First you split the DEPENDS at the colon.  The part before
the colon is used to check wether a suitable package is already
installed (or which binary package to pull in when using pkg_add).
The second part is used to build the dependency from source.

  So the above means to: perl>=5.10 and p5-Module-Build=>0.2608nb1 can
be used satisfies the dependency, so if either is installed, we're
done.  Otherwise, go to ../../devel/p5-Module-Build and install from
there to fulfill this dependency.
