preinstall_error

[Babak Farrokhi]

Hello,

Every once in a while I get preinstall_error in my tinderbox. But when
build enters the second phase ( retries the build ), the build
completes successfully. Log file reads:

====================<phase 5: make test>====================
make: don't know how to make regression-test(continuing)
================================================================
Fatal error: filesystem was touched prior to 'make install' phase
ccache.log extra
================================================================

The problem seems to be related to ccache, but I couldn't figure out what is it.

Have anyone else seen this issue before?

Thanks
