Ah, I guess those guys included the glibconfig.h file that sunfreeware 
forgot.

That is the correct first step.  That will give files with "null" CPU 
util and processor affinity calls.

Libtool bug perhaps, or was there an actual --export-dynamic in one of 
the ".am" makefiles?

That's OK, neither do I :)

Hmm, seems that solaris dumps core where others might not.  You can use 
the -L option to specify the local control endpoint stuff.  As a start 
you can try -L localhost  so  src/netserver -L localhost

Make sure that "netperf4" is in /etc/services or whatever your system 
uses to lookup service names.

Also make sure that /etc/xml/catalog got updated during the make install 
to include an entry for netperf.
