>Description:
In my /etc/make.conf, I use '.include' to bring in /etc/make.conf.ports, so that I can have the port specific variables in a seperate file.

The problem is that when I install one of the lang/perl5* ports, it modifies /etc/make.conf, so that it can place its PERL_* variables in it.  I would prefer to have these variables added to /etc/make.conf.ports.
>How-To-Repeat:
Create a /etc/make.conf file similar to the one below: 

# default /etc/make.conf
.if ${.CURDIR:M/usr/src/5x/*}
.include "/etc/make.conf.5x"
.elif ${.CURDIR:M/usr/src/7x/*}
.include "/etc/make.conf.7x"
.else
.include "/etc/make.conf.6x"
.endif

# ports
.if ${.CURDIR:M/usr/ports/*}
.include "/etc/make.conf.ports"
.endif

Then install one of the lang/perl5* ports, and see that /etc/make.conf has been modified.
>Fix:
I have created a patch that adds:

PERL_MAKE_CONF?= __MAKE_CONF

and then changes the substitution for use.perl to use PERL_MAKE_CONF instead of __MAKE_CONF.  This allows the port to use an alternate file to place the PERL_* variables in.

see patch in following email.
