i also run into the same problem, according to qmailtoaster installation script the command suppose to be
rpmbuild --rebuild --with cnt5064 vqadmin-toaster-2.3.7-1.4.1.src.rpm
built it has the same error msg as above
and I Google around and found out
many of our programs are running automake versions that PREDATE 64-bit linux... and while most apps will build just fine (albeit less optimized), vqadmin 2.3.7 does NOT build successfully in this "unknown-linux" environment.
He offers a x86_64 rpm at the bottom
