    #see http://www.iana.org/assignments/port-numbers

    #you must have already installed one of these (they are the same considering the functionality gain): 
    https://adrhc.go.ro/ffp_0.7_armv5/packages/iana-etc-2.30-arm-0.txz -> this one has more comments (compared with stripped version)

#Install CPAN minus module
wget http://search.cpan.org/CPAN/authors/id/M/MI/MIYAGAWA/App-cpanminus-1.7023.tar.gz
#In order to work CPAN minus requires:
#ln -s /ffp/etc/protocols /etc/protocols
#CPAN minus might require Mozilla's CA Bundle certificate (search /ffp/bin/cpanm for cert.pem after installation).
#download the Mozilla's CA Bundle certificate:
#wget -nv http://curl.haxx.se/ca/cacert.pem -O /ffp/etc/ssl/cert.pem

#Install cpan-outdated module:

#In order to learn about outdated modules run:

#Install cpanlistchanges with CPAN:
cpan install App::cpanlistchanges

#When building help2man and perl has the module Locale::gettext I get the error:
#sh: error while loading shared libraries: libintl.so.8: cannot open shared object file: No such file or directory
#solved by (adding /ffp/lib to the end):
#export LD_LIBRARY_PATH=/usr/local/zy-pkgs/lib:/ffp/opt/serf-1.3.6/lib:/ffp/lib
#and also the error:
#help2man: can't get `--help' info from ./help2man
#Try `--no-discard-stderr' if option outputs to stderr
#solved by removing Locale::gettext perl module:
perl ~/tools/uninstall_perl_module.pl Locale::gettext -> only shows what files should be removed
#then remove by hand the Locale::gettext specific files
