LinuxQuestions.org - self build rpm fails with missing dependencies on build host

Hi folks,

as I'm advancing in building some nice rpm I finally wanted to install on of my gems also the build was successful the actual install fails with missing dependencies.

Code:

$ rpm --root /home/sascha/rpmbuild/ -i ./RPMS/x86_64/memcached-1.4.1-2.x86_64.rpm

error: Failed dependencies:

    libc.so.6()(64bit) is needed by memcached-1.4.1-2.x86_64

    libc.so.6(GLIBC_2.2.5)(64bit) is needed by memcached-1.4.1-2.x86_64

    libc.so.6(GLIBC_2.3)(64bit) is needed by memcached-1.4.1-2.x86_64

    libevent-1.4.so.2()(64bit) is needed by memcached-1.4.1-2.x86_64

    libpthread.so.0()(64bit) is needed by memcached-1.4.1-2.x86_64

    libpthread.so.0(GLIBC_2.2.5)(64bit) is needed by memcached-1.4.1-2.x86_64

    libpthread.so.0(GLIBC_2.3.2)(64bit) is needed by memcached-1.4.1-2.x86_64

libevent is not that problem it's needed for the build I just build another rpm for this ;) but whats causing me headache is why libc is needed?

Anyone any ideas?
