horizon by default uses lesscpy (python) instead of lessc (javascript).
Obviously lesscpy did not like our less code.
So we changed this:
COMPRESS_PRECOMPILERS = (
('text/less', 'lesscpy {infile}'),
)
To this:
COMPRESS_PRECOMPILERS = (
('text/less', 'lessc {infile} {outfile}'),
)
lessc likes our less code more and it works!
