and after typing : install http::proxy it seemed to install ok

• what was it that gave you the impression it did?
• do you have some output of the install process? did you read it?
• ask yourself - what bits of information are missing from your post to make me not point towards some general direction, e.g. equator, roughly?
• have you seen How do I post a question effectively?

In other words - well, perl seems to be unable to find the file HTTP/Proxy.pm. I could only throw in wild guesses about why it can't without further information from you (perl version, install log, OS version and so on...)

Check the perl include path typing perl -V at a cmd prompt and search in the directories shown there for a directory HTTP and a file called Proxy.pm in it. If you can't find it, the package wasn't installed successfully.
