Does somebody know whether (and how) I can convince Sage to work with an
existing FriCAS (compiled with sbcl) instead of compiling+installing the

If this is a call for a vote ;-), let me tell that I completely agree with the
point of view that in an ideal world, tests should be written *before* the
code and by a *different* person (extreme/peer programming).
In an ideal world test would be extracted from theorems of theoretical
papers. A

Same for FriCAS. It should be fricas-1.0.8.

And why would "1 + 2" be wrong/bad or whatever?
Can you give a suggestion what I must input to sage to exacly get an
expression 1+2 in sage, i.e. an expression tree
