I've gotten the latest picolisp, 3.1.9, and am trying to install locally.
Following the instructions for 64-bit on my linux, I've built the
executable picolisp all right. But the bin directory's pil seems to pick up
the previous version I installed before from Ubuntu:
-> (3 1 7 3)
However the pil in the .../picolisp/ main directory does work, giving
-> (3 1 9 0)
Why does the pil in .../bin/ behave this way? I'd like both, but I guess I
could uninstall one of them. . .
