in reply to perl multitouch module error

Welcome. Before answering your question plesae read and understand How do I post a question effectively?. Code, data and errors should be within code tags, for example:

<code> code, data and errors go here </code>

The easier you make it for people to help you, the more likely they are to do so. taint raises valid points regarding perl, but it seems like tere are a lot of PHP errors.

If you are using a program which has PHP as well as Perl dependencies you need to satisfy them both. A wise approach would be to add code tags, read and understand How do I post a question effectively? then actually tell us what code you have which is producing these errors. Without this information people can only offer very general advice.
