Issue during compilation

[Thomas Nguyen Van <t.nguyenvan@jumper.ie>]

Afternoon,

My company just bought an ADSL card referenced "Sangoma S518 ADSL Card".

I'm trying to install it on a Debian/Lenny (Linux 2.6.26-1-686). So I typed the command: 

/tmp/wanpipe-3.2.7.1/Setup builddeb

However after few seconds, I got the following message:

WANPIPE DRIVER COMPILE LOG

Does anyone have any clue to solve such a problem?
Many thanks in advance

Thomas
