New description:

 `$HOME` can be slow in case it is NFS-mounted for example. So using local
 scratch space or even better a RAM disk should speed up the build by a
 nice factor. To do so, use `$SAGE_BUILD_TMPDIR/build/` in case it exists
 instead of `$SAGE_ROOT/spkg/build/`.

 ----

 Apply [attachment:trac_4949-scripts.patch] to the Sage '''scripts
 repository'''.

 Apply [attachment:trac_4949-installation.patch] to the '''Sage library'''.

 '''After applying, replace the bootstrap version of `sage-spkg` in
 `$SAGE_ROOT/spkg/base/` with the new version.'''
