Memcached: "no such file to load -- memcache-client" when running script/console

Rails
1

Hi folks. I’ve started down the memcached path and everything was
running grand until I decided to start up my console. I have manually
installed libevent 1.4.13 and memcached 1.4.4 into /usr/local,
following which I sudo gem installed memcache-client and SystemTimer.
development.rb has been modified to do caching with the
mem_cache_store.

The memcached process seems to work and my script/server starts up
fine. However, when I try script/console, I get the errors pasted at
the bottom of this post. If I test out some cache commands such as
Rails.cache.write(‘foo’, ‘bar’), Rails.cache.read(‘foo’) they do work
correctly.

Any enlightenment appreciated.

I’d like to add that when I run script/server, I am getting the same
errors but only with SystemTimer.

This is what happens when you code at 2am. After banging my head
against the wall for half an hour, I discovered the error was due to a
typo in my config.gem requirements. Ugh, Goodnight.
