Problem with aclocal, pkg.m4 and ports

[Bruce M Simpson]

Hi,

I basically just ran into the same problem as this guy did, whilst 
trying to roll a FUSE port:
    
http://lists.freebsd.org/pipermail/freebsd-questions/2008-April/172377.html

It seems if I run the *same* aclocal binary from the command line, 
pkg.m4 is expanded in aclocal.m4 inside WRKSRC. But if I let it run from 
the Makefile targets, it doesn't.

What's going on?  I have reworked the port in progress to just push 
CPPFLAGS in the environment, obviously this isn't "the pkgconfig way".

thanks,
BMS
