Ah, you are running into fun with RH9's NPTL (New Posix Threads 
Library).  If you look at the archives for this list you will find some 
discussion about it.  I believe the quick and dirty solution was to 
compile DB4 with a flag telling it to assume phtreads were not 
available, but Simon also posted a link to a discussion at RedHat about 
more general issues with NPTL.

The particular errors you are getting are because it can't find the 
pthreads library when it does the test.  You can fix that by telling 
configure to use -lpthreads on any compiles, but if I remember correctly 
you will then run into other issues when DB4 tries to do some operations 
on the threads.

I am staying with RH8 for my production machines because of this and a 
few other minor issues.
