undefined reference to `clock_gettime'

[Tim Boyer]

I'm trying to install 4.2.3 to a RHEL5.3 system.  make returns the
following:

../lib/hobbitclient.a(timefunc-client.o): In function `gettimer':
/usr/src/xymon-4.2.3/lib/timefunc.c:55: undefined reference to
`clock_gettime'
../lib/hobbitclient.a(timefunc-client.o): In function `getntimer':
/usr/src/xymon-4.2.3/lib/timefunc.c:67: undefined reference to
`clock_gettime'
collect2: ld returned 1 exit status

I've seen a couple of posts that suggest I add

LIBRTDEF = -lrt

to the Makefile.  I've done that, and it gets worse...

Pointers in the right direction appreciated.
