Trying to install popa3d. Whenever I do the command:

groupadd popa3d

I get:

/usr/sbin/nscd: relocation error: /usr/sbin/nscd: symbol __nss_services_lookup, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
/usr/sbin/nscd: relocation error: /usr/sbin/nscd: symbol __nss_services_lookup, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
/usr/sbin/nscd: relocation error: /usr/sbin/nscd: symbol __nss_services_lookup, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

What's wrong and how do I fix it???

And how do I add a template user???
