[SCIP] Help with setting up parallel solve in pyscipopt

Hello All,     I'm new to SCIP and wanted to try running with concurrent opt mode.  I'm working on Linux and was able to install the scip package via cond-forge, but when I attempted to use the parallel functionality via solveConcurrent(),  
I received the following warning:
UserWarning('SCIP was compiled without task processing interface. Parallel solve not possible - using optimize() instead of solveConcurrent()')

I read that by default SCIP isn't compiled with the TPI option, so went through the process of building it after much fumbling around.I can solve problems via command line with parallel mode with the rebuilt version.
My question now is how to I tell psyscipopt to use that version?  I naively created a symlink to point the version of scipt in my virtual environment to the rebuilt version, but still running into the same problem.
Any help would be appreciated.
Thanks,Hon Fai
