Just a quick FYI: If you haven't already gotten Fedora 15's latest glibc-headers package, you may want to wait for 2.13.90-11. Here's why: glibc-headers-2.13.90-10.x86_64 no longer includes any of the /usr/include/rpc/*.h files. Contrast with glibc-headers-2.13.90-9.x86_64, where there are 18: $ rpm -ql glibc-headers|grep -cw rpc 18 I noticed because now, anything that includes at least <netdb.h> is no longer compilable: $ echo '#include <netdb.h>' > k.c && gcc -c k.c In file included from k.c:1:0: /usr/include/netdb.h:33:24: fatal error: rpc/netdb.h: No such file or directory compilation terminated.
