EXRUN insufficient when variants used

[jrmarino]

example port split into subpackages:

• complete
• primary
• dev
• tools
• man

If there are multiple variants (standard and dos) and EXRUN[tools]= example:primary:standard, then example:tools:dos will try to pull in example:primary:standard instead of example:primary:dos subpackage.

ravenadm has to figure this out and link to the proper one.

[jrmarino]

so probably it should be designed that if the value of the exruns has no colons in it, and it matches a subpackage, it should be constructed.

in this example:

EXRUN[tools]= primary. for the standard variant, this goes to example.tools.standard pulls in example.primary.standard and example.tools.dos pulls in example.primary.dos

Release 2.07 is out with this fix.
