I'm afraid the new 2.19.0 portlint brought some regressions. For example, running `portlint -C` in lang/gcc10-devel or emulators/wine-devel results in (and seems to abort early): Modification of a read-only value attempted at portlint line 1977. The line in question reads my $srex = chomp($1); This is with Perl 5.26.3, for example on ref11-i386.
