 This is not an error but just about a (MacPorts?) patch that was
 ineffective.

 During an installation, ghostscript @9.19_0+x11 was installed. The
 installation log contained the following warning.

 }}}
 These are my conclusions:

 It's about patching the '''shebang''' of the file
 '''/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_print_ghostscript/ghostscript/work/ghostscript-9.19/freetype_local/src/tools/afblue.pl'''

 Obviously, the '''sed''' expression intends to change the path to the PERL
 interpreter in the file '''afblue.pl''', however, said file contains an
 unexpected space so the regular expressions does not match, as can be seen
 here:

 {{{
 $ head
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_print_ghostscript/ghostscript/work/ghostscript-9.19/freetype_local/src/tools/afblue.pl
 #! /usr/bin/perl -w
 # -*- Perl -*-
 #
 # afblue.pl
 #
 # Process a blue zone character data file.

 }}}
 Mind the space between "#!" and "/usr/bin/perl".
