beanstalkd: gmake should be a build, not library, dependency

[ryandesign@…]

beanstalkd declares a library dependency on gmake:

$ port deps beanstalkd
Full Name: beanstalkd @1.4.6_2
Library Dependencies: libevent1, gmake

It looks like this was added in r33535 to fix build issues on Tiger; presumably its included version of gmake is too old.

Since MacPorts still works on Tiger we should retain this dependency. However, gmake is a program typically used to build other programs. It is not a library and is not typically used at runtime. So it should be a build dependency, not a library dependency.
