Yes. We need to find ways of reducing the amount of disk space used on the buildbot workers, especially the pre-10.9 workers which need more space to activate the many versions of clang needed to build C++11 ports. Some ideas include:

Using hfsCompression:
https://trac.macports.org/ticket/57396
(This is ready to be deployed, but has not been deployed yet.)

Not keeping large ports installed and/or not keeping ports installed that have no dependents:
https://trac.macports.org/ticket/57464
(This has not yet been implemented.)
