Orthofinder failure when running test dataset

[devonorourke]

Hi,
I've tried running ORP through the Conda installation method proposed here, as well as an alternative installation where I manually installed each piece separately following the same steps offered in this repo's Makefile. In each case I get the same error such that the program completes all steps through the spades and transabyss assemblies, but fails once OrthoFinder gets rolling. Then I get this error message:

Test can run "mcl -h" - failed

What's confusing is that MCL is indeed accessible:

$ which mcl

/scratch/dro49/conda/envs/orp/bin/mcl

and MCL can indeed access the help menu (thus the ERROR: Cannot run MCL with the command "mcl -h" is very confusing!

$ mcl -h

________ mcl verbosity modes
--show ....... print MCL iterands (small graphs only)
-v all ....... turn on all -v options
________ on multi-processor systems
-te <i> ...... number of threads to use                                  [0]

further, I know I've loaded the missing glibc module...

$module list

Currently Loaded Modulefiles:
  1) git/2.16.3          2) anaconda3/2019.10   3) binutils/2.28       4) glibc/2.14

Any ideas what could be breaking here?
Thanks!
