Trying to build curl on Fedora 13 consistently fails with:

/bin/sh ../libtool --tag=CC --mode=link gcc -O2 -g0 -Wno-system-headers

If I add the librt library to the command, it works:

[root_at_zre-f13-64 src]# gcc -O2 -g0 -Wno-system-headers -o .libs/curl main.o
hugehelp.o urlglob.o writeout.o writeenv.o getpass.o homedir.o curlutil.o

-lrt -pthread -Wl,-rpath -Wl,/opt/zimbra/curl-7.21.1/lib -Wl,-rpath
-Wl,/opt/zimbra/openssl-1.0.0a/lib -Wl,-rpath
-Wl,/opt/zimbra/heimdal-1.3.3/lib

I don't have this issue on the other 20 or so OSes I build curl on. Any
idea why curl is failing to pick up librt?
