reduce-algebra does not find any packages

[veedeehjay@…]

I did a port -s install reduce-algebra (binary install is broken, see ticket ​https://trac.macports.org/ticket/34895) which completes without errors.

opt/local/libexec/reduce-algebra/bin/redpsl starts up and basic things work. but the (reduce) package loading mechanism fails, e.g.

taylor(1/x,x,1,2);

leads to the error message * error in loading package taylor or package not found

I have searched around a bit and the problem might not be directly macports related but there seems to be no public mailing list for reduce. so maybe somebody around here can find a solution...
