[syslog-ng]compile problem HAVE_RES_INIT

[ktb]

I'm trying to compile syslog-ng-1.5.23 on a RedHat 6.0 machine.  When I
run "make" I get the following error -

make[1]: Entering directory `/usr/local/src/syslog-ng-1.5.23/src'
cd /usr/local/src/syslog-ng-1.5.23 && autoheader
/usr/bin/autoheader: Symbol `HAVE_RES_INIT' is not covered by /usr/share/autoconf/acconfig.h ./acconfig.h
make[1]: *** [/usr/local/src/syslog-ng-1.5.23/src/stamp-h.in] Error 1
make[1]: Leaving directory `/usr/local/src/syslog-ng-1.5.23/src'
make: *** [all-recursive] Error 1

Anyone know how I can get around this error?
Thanks,
kent
