RPM Install, failed dependencies even though files exist: SUN Opteron, Linux RedHat x86

Question : RPM Install, failed dependencies even though files exist: SUN Opteron, Linux RedHat x86_64

I am trying to install ypserv-2.19.-2.x86_64 onto a SUN Opteron system with Linux x96-64 (2.6.9-34ELsmp) and I keep getting the message

error: Failed dependencies:
libc.s0.6 (GLIB_2.4) (64bit) is needed by ypserv-2.19.-2.x86_64
rtld (GNU_HASH) is needed by ypserv-2.19.-2.x86_64

…if I do a find, I find a number of copies inclusing a 64 bit version

/lib/i686/libc.so.6
/usr/lib64/libc.so.6
/lib/libc.so.6
/usr/lib/libc.so.6

…AND, I also have all the above in both my LD_LIBRARY_PATH and my PATH.

Any ideas?
Thanks!

for src.rpm (source rpm, not binary rpm) please use
rpmbuild –rebuild ypserv-2.13-9.src.rpm
them
rpm -ivh ypserv-*.x86_64.rpm
