Sorry... I forgot to answer the grep question: yes.

Interpreted Languages

Usually interpreted languages will fail to run if a required module is
not installed.

    * Perl modules are usually referenced as foo::bar (for example
xml::parser). However, the package is called libfoo-bar-perl
(libxml-parser-perl). Searching via apt-cache can help if this naming is
a bit different, for example:

apt-cache search foo | grep bar
apt-cache search xml | grep parser

    * Python modules are named python-module, so the python mysql module
would be python-mysqldb. The mapping is less consistent here and
apt-cache will help a lot. Doing a search like

       apt-cache search python | grep mysql
