[OpenAFS] Trouble compiling 1.4rc4 SRPM
Fri, 30 Sep 2005 14:54:03 -0400
Actually, it turns out that just removing res_search causes
the RPM to fail to build on RHEL3.. So.. I think I need to
take this route and search for both res_search and __res_search.
I'm testing it now on EL3.. But then I suspect I'll have to go
back and rebuild FC1,3,4. Feh!
