lang/perl5.8 use.perl wipes away /etc/make.conf

[Sergei Vyshenski]

Hi,

portupgrade -f perl-5.8.8_1 

erases from /etc/make.conf
all lines, which contain literals "PERL",
including lines:

WITHOUT_PERL_MALLOC=yes

WITHOUT_USE_PERL=yes

and replaces all of them with just 3 lines:

# added by use.perl 2007-11-19 13:34:51
PERL_VER=5.8.8
PERL_VERSION=5.8.8

This seemingly violates an idea, that everything
put by hand into /etc/... should be kept intact.
If this is an intended behavior of the port, 
could you please recommend how to go around this.

All the best, 
Sergei
