Install Perl by running the following commands:
./Configure -Dprefix=/usr &&
make &&
make install
If you don't want to answer all those questions Perl asks you, you can add the -d option to the configure script and Perl will use all the default settings.
Also note that a few tests during the make test phase will fail for various reasons. One being there's not network support yet and a few packages haven't been installed yet. It's ok if not every test succeeds. If there are between 5 and 10 failed tests you're just fine. You might want to reinstall perl after you're done with chapter 7.
The Perl package contains Perl - Practical Extraction and Report Language
Perl combines the features and capabilities of C, awk, sed and sh into one powerful programming language.
