Moving to Equinox/p2
Attempted to install a plug-in again. I'm going to be integrating with source control and defect tracking soon, so I would like this addressed.

Finally found a solution referencing another bug: adding -startup plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar to eclipse.ini seems to have solved problem.
