Yes. The build procedure for scala uses multiple phases to ensure that
the code cleanly bootstraps.  The sequence is like this:

bootstrap (starr) -> locker -> quick -> strap

The results of the quick phase are packaged.  The results of the strap
phase are compared byte-for-byte with the resuts of the quick phase to
ensure that the compiler is stable.

For more details, see http://tinyurl.com/3e3l55 which is the README of
the source distribution.  It describes in detail the process used to
build scala.  I use this process unaltered when building the RPM.
