# We remove the old Perl from the system before building
rm -rf /usr/lib/perl5

# Extract the source code:
cd $TMP
rm -rf perl-$VERSION
tar xvzf $CWD/perl-$VERSION.tar.gz

# Configure the source code:
cd perl-$VERSION

# Adjust owner/perms to standard values:
chown -R root.root .
find . -perm 555 -exec chmod 755 {} \;
find . -perm 444 -exec chmod 644 {} \;

# It is often suggested that we add this to the ./Configure:
#            -Dusethreads \
# However, this option is considered experimental, and is not
# recommended for production systems.  As such, we can't add
# to our default perl build.  If you want the option anyway,
# just add it below and rebuild perl.

# We no longer include suidperl.  To quote the INSTALL file:
#
#   Because of the buggy history of suidperl, and the difficulty
#   of properly security auditing as large and complex piece of
#   software as Perl, we cannot recommend using suidperl and the feature
#   should be considered deprecated.
#   Instead use for example 'sudo': http://www.courtesan.com/sudo/

# Configure perl:
            # -Dinstallprefix=/tmp/package-perl/usr
./Configure -de \
            -Dprefix=/usr \
            -Dcccdlflags='-fPIC' \
            -Darchname=i486-linux 

# Build perl

# There are also miniperl and microperl.
# I haven't had any requests for them, but would be willing
# to consider adding one or both to the package if anyone
# actually needs them for some reason.
