[imp] "Constant pear_error_return already defined" PROBLEMS

[Radek]

Hello All!

I installed the latest version of imp and everything seems to be
working fine except for the Compose window which - when launched -
gives me the following list of errors:

Warning: Constant pear_error_return already defined in

Any suggestions?
