I do see a mention of modification "…modifications are clearly marked." 
Compare with the gnuplot license, for which modifications can only be 
distributed as separate patch files

ajam clearly marks its modifications by including this in its readme:

"""
This if "Argyll-Jam", a simple derivative of the "FT-Jam" build tool, based and
100% compatible with Jam 2.5. See http://www.freetype.org/jam/ for more
details about FT-Jam.

This is the "FT-Jam" 2.5.2 release, with minor ArgyllCMS tweaks,
and the ArgyllCMS V1.3.3 Jambase as the default rule set.

Note that you'll find the original Jam README in the file README.ORG
"""

Thoughts?
