Problem calling Net::FTP

[Pascal TRONQUET]

I'm running on NT4.
When I run my Perl program from the NT account ORLEANS\CONTROLM  (domain\id)
it works fine, but when I'm calling it through the BMC software ControlM
I get :
    Can't locate Net/FTP.pm in @INC at versaxys.pl line 29
    Begin failed - compilation aborted at versaxys.pl line 29

The software ControlM is supposed to start my program with the same NT
account (ORLEANS\CONTROLM).

Line 29 contains " use Net::FTP;  "

Does anyone have an idea ?
