Hey, Vince!
 
From the looks of things, you're using a not-quite up to date version of
the source. If you haven't already, grab the version I released last night;
it's been extensively tested under RedHat 8.0 and a lot of your feedback
was used for making some prospective changes. 
 
The header I'm interested in is probably either sys/types.h or time.h. I'm
hoping that your flavour of Linux has a __timer_t_defined define in it like
the newer RedHat distros. 
 
I also tested under gcc 3.2 -- ouch. No wonder you couldn't build it, man
it was a pain getting it going. :)
 
Let me know how things go for you -- we'll get it going eventually. :)
 
Cheers,
Wes
