Change worksrcpath for build phase

[justin t]

Hi,
I'm trying to configure and build in a custom directory. I don't want to configure/run in the source tree. My pre-configure correctly cd's into ${worksrcpath}/buildTree, which I created, but my pre-build phase doesn't work. It still cd's into ${worksrcpath}.
pre-build {    file mkdir                   ${worksrcpath}/buildTree    set worksrcpath          ${worksrcpath}/builtTree}
Thanks,Brandon
