[asterisk-users] [FreeBSD 6.2] Error compiling Zaptel from Ports?

[Vincent]

Hello

I'm trying to build the Zaptel ports on FreeBSD, but it fails:

==========
# cd /usr/ports/misc/zaptel/
# make install

===>  Building for zaptel-1.4.6_3
make -C zaptel all

Has someone seen this and knows what to do?

Thank you.
