>Description:
Perl 5.8.0_6 is installed. Tried to make package with latest perl (5.8.2) which failed but /usr/local/bin/perl was deleted.


>How-To-Repeat:
Perl 5.8.0_6 installed.
cd /usr/ports/lang/perl5.8
grep PERL_VER= Makefile
PERL_VER=       5.8.2
make package

>Fix:
Rev 1.65 of the Makefile introduced a pre-install target that deletes
${PREFIX}/bin/perl (and PERL_VER).

Surely this is against POLA.
I do not expect make install (or package) to delete anything in the installed system.
The CVS log indicate that this was done to overcome weird symlinking possibly from portupgrade.  *IF* this is the case then fixing portupgrade would be preferable.

Should not the perl ports install the actual perl binary as perl${version} and just have perl a symlink to the version?
Rather than the current:
-rwxr-xr-x  1 root  wheel  811876 Apr 29  2003 perl*
lrwxr-xr-x 1 root wheel 19 Mar 31 10:20 perl5@ -> /usr/local/bin/perl
lrwxrwxrwx 1 root wheel 19 Mar 31 10:20 perl5.8.0@ -> /usr/local/bin/perl
