Sangoma wanpipe and Asterisk 1.4

[Liviu Toma]

Hello,

Has anybody installed the Sangoma wanpipe drivers with Asterisk 1.4 ?
(I am using CentOS 4.4).
My setup works OK up to the point where it's trying to compile the
wanpipe tools and it fails with the message:

               !!! WANPIPE Tools Compilation Failed !!!
       Possible solution:
                Wanpipe header files were not installed properly
                in /lib/modules/2.6.9-42.0.8.EL/build/include directory
       Please contact Sangoma Tech. at 905 474-1990

Any idea ?

Thanks,
Liviu
