OK, thanks for getting back to me, and I am learning...

Nevertheless: this sounds terribly complicated to me.

Why would I use a package manager then (the guix package manager i.e.) in the
first place, if I can install idris2 in just simple three steps:


step 1
download https://www.idris-lang.org/idris2-src/idris2-0.5.1.tgz
and unpack it.

step 2
adjust PREFIX in config.mk therein ($(HOME)/opt/idris2 in my case)
and set PATH, and LD_LIBRARY_PATH accordingly:

  export PATH=$PATH:$HOME/opt/idris2/bin
  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/opt/idris2/lib

step 3
(assuming racket is installed - as in my case):

  make bootstrap-racket
  make install


And In particular: there is no Idris1 involved.

(And by the way: the pregenerated scheme in there is not a binary,
it is readable scheme code after all - well not terribly readable,
but nevertheless).

What is won with the extra step of having an older Idris2 installed
first, that still compiles with Idris 1 - And then do what with that:
compile a newer Idris2 from that (that may still not be sufficiant
to compile the latest Idris2), ... Reproducibility ? - Certainly
not simplicity!

But apparently: you are more experienced in these packaging matters
then me.

So thanks - in any case.

And by the way: my bench marks were on a 8 core
Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz
running Debian testing)
