I think this is a reasonable bug report. The fix is for Sage to
include the cached precompiled versions of the Magma files.
It used to be with Magma that one had to start it up as root
once because they didn't include precompiled files. I think
this has changed, i.e., I think they now ship the precompiled
cached files in addition to the source files.
