Hi, I'm trying to install it in my 64 bits Ubuntu host with Ruby1.9.1 
installed from sources in /usr/local.

This is the error output I get after doing "gem install localmemcache":


/usr/local/bin/ruby1.9 extconf.rb install localmemcache
checking for main() in -lrt... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib
        --with-make-prog
        --without-make-prog
        --srcdir=.
        --curdir
        --ruby=/usr/local/bin/ruby1.9
        --with-rtlib
        --without-rtlib

You have to install development tools first.

mkmf.log is empty. What could I check?
Thanks.
