Porting question

[Larry Rosenman]

I've asked portmgr before, but still haven't found a decent way to do what I
want, so let me post this publicly.

I want to make the sysutils/lsof port fail early with a decent message if
the kernel sources aren't loaded on the system.

The most common question/problem report I get is when the lsof configure
script fails due to a lack of the system sources. 

Ideas on how to do this cleanly in the port Makefile?

Thanks!
