Thank you for naming the specific software package, and showing the

There are no restrictions specified (so we have only the restrictions
from copyright law). That explains, I think, the extreme brevity of the
text: it grants freedoms without specifying any conditions.
The license to redistribute in source or binary form is unconditionally
granted (required for DFSG §2).
The license to modify is unconditionally granted (required for DFSG §3).
However, the license to redistribute derived works is not granted (this
violates DFSG §3). By the deliberately emphasised “ORIGINAL package”,
this is apparently a deliberate exclusion on the part of the authors of

By this analysis, the work is not DFSG-compatible and is not free software.
