Hi,

I'm trying to Install Memcached-libmemcached-1.001702 via cpan on a Gentoo 2.2 with perl 5.18.2 but it fails at:

CXX      libtest/libtest_libtest_la-tmpfile.lo
libtest/server_container.cc: In member function 'libtest::Server* libtest::server_startup_st::create(const string&, in_port_t, bool)':

Makefile:9312: recipe for target 'install' failed
make: *** [install] Error 2
Unable to build libmemcached: Error running cd src/libmemcached && make install

Aborted.

-> FAIL Configure failed for Memcached-libmemcached-1.001702.

Currently there is Memcached-libmemcached-0.4406 installed and a memcached server running.

Thanks in advance for any advice on how to deal with that problem.

Best regards,
Thomas
