Why does samba think it (R)DEPENDS on perl?

Why does samba think it (R)DEPENDS on perl?

[Mike Looijmans]

When building the current version of samba, it builds perl and drags it 
into the image through an RDEPENDS.

I've been researching this for a while, but failed to figure out what 
causes this runtime relation. Is there a way to find out where this is 
being "detected"?

The workaround I implemented is simply adding this line to the samba 
recipe, which at least gets rid of the overhead in the image:

RDEPENDS_${PN}_remove = "perl"

(Samba 4 is bloated enough by itself, it doesn't need other packages to 
inflate its runtime even more)

Found that the cause is "inherit cpan-base", this hardcodes "perl" into 
the package.

I think this requires a split-up of cpan-base.bbclass into two parts, so 
that one get obtain the perl version without adding these dependencies.

It's more reasonable to "move" the RDEPENDS from cpan-base.bbclass to cpan.bbclass and cpan_build.bbclass (WITH commend in source).
cpan-base.bbclass might be an unfortunate place for adding RDEPENDS, since it's just a helper (abstract base class ^^)
