[Bioperl-l] problem in using protparam.pm module

[Ulrik Stervbo]

I had the same problem, and realized it is because I am behind a proxy.

This is what I did to the Protparam module:
Changed the url to 'http://web.expasy.org/cgi-bin/protparam/protparam'
as previously found

Added:
$browser->proxy(['http'], 'http://[my proxy]/'); after initialization
of the LWP agent.

The proxy settings is what made Perl choke. (If only one could make
perl see global proxy settings).

Cheers,
Ulrik
