[system-traders] Scan.pl problem

[Piero Cevola <pirrow AT tin.it>(by way of Piero Cevola <pirrow AT tin.it>)]

Hi to all!
i'm an italian economy degree and i've just finished to install GT and a
beancounter db in postgresql to store my data.

I tried some functions to use the scan.pl script and all was ok also with 
beancounter.

But now when i start the scan script (./scan.pl namelist date systemfile)
independently by the functions that i use GT says:
"Can't call method "rcv" on an undefined value at ./scan.pl line 114, <> line
1."

Some one can help me?.. I didn't change nothing on my system and i don't
understand what happen...

Cheers
Piero
