Building CSS::LESS on OS X - macos

Question

Anyone successfully installed CSS::LESS on OS X?
For me it failed with many errors, like the next one:
$ make test
/Users/me/perl5/perlbrew/perls/perl-5.16.3/bin/perl Build --makefile_env_macros 1 test
t/00.load.t ................. 1/1 # Testing CSS::LESS 0.0.3
t/00.load.t ................. ok
t/10.dry-run.t ..............
# Failed test '"include_paths" parameter (set to constructor)'
# at t/10.dry-run.t line 20.
# 'lessc /var/folders/7l/nhyscwy14bjb_sxr_t2gynpm0000gn/T/RoPSlWoxEQ --include-path=/Users/me/.cpanm/work/1395039258.75205/CSS-LESS-v0.0.3/t/foo/:/bar/ --verbose --no-color'
# doesn't match '(?^:^lessc /tmp/\w+ --include-path=/Users/me/.cpanm/work/1395039258.75205/CSS-LESS-v0.0.3/t/foo/:/bar/ --verbose --no-color$)'
IMHO, this is a case of a wrong test expectations, because on OS X the tempfiles are created in the /var/folders/.... and not in the /tmp.
Similar error reports are in the www.cpantesters.org . EXPECT ONE here: http://www.cpantesters.org/cpan/report/dac3ce8e-3c79-11e3-aac4-3cf3dfeaf78b
Asking this question because if it is somewhat possible build the CSS::LESS os OS X would be happy to know - how.
EDIT
Hm, the above successful test report (and the Module itself) is strange, because
# Testing CSS::LESS 0.0.3
t/00.load.t ................. ok
t/10.dry-run.t .............. ok
t/90.lessc_compile.t ........ skipped: Not installed lessc
t/91.lessc_compile_error.t .. skipped: Not installed lessc
^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - the module DEPENDS on 'lessc'
t/92.lessc_not-installed.t .. ok
All tests successful.
Files=5, Tests=8, 1 wallclock secs ( 0.03 usr 0.02 sys + 0.29 cusr 0.06 csys = 0.40 CPU)
Result: PASS
but, regardless of the missing lessc (what should be an error, because the module depends on it) the test
t/10.dry-run.t .............. ok
finished as OK - and on my system throws an error.

Answer 1

Found myself a partial answer for the question.
The test is probably somewhat depends on the $TMPDIR shell variable. On OS X defaultly this wariable points to an directory what is unique to every logged user, and resides in the /var/folders/..., like this:
$ echo $TMPDIR
/var/folders/7l/nhyscwy14bjb_sxr_t2gynpm0000gn/T/
When manually changed the default value of $TMPDIR to /tmp, with:
TMPDIR=/tmp/
and run for CSS::LESS
perl Makefile.PL
make
make test
got
/Users/me/perl5/perlbrew/perls/perl-5.16.3/bin/perl Build --makefile_env_macros 1 test

make: *** [test] Error 255
The subtest
t/10.dry-run.t .............. ok
is no problem anymore. Anyway the module didn't built - but throws another (lessc) error.
So, Neil Bower (a sumbitter of the "successful" test report) probably changed the $TMPDIR too. And because he hasn't installed the external command lessc got a successful result.
Demostration:
$ sudo mv /opt/local/bin/{lessc,lessc1} #rename lessc to lessc1

Great :) - unfortunately - this is a FALSE result, and the CSS::LESS didn't builds OK on OS X.
