[Caml-list] cannot create new opam switches

[Ian Zimmerman]

I am currently on ocaml 4.07.1.  When I try to create an opam switch for
anything (and I mean anything) newer, I get the following:

 matica!21 ~$ opam switch create 4.10.0

Ok, I got it.  Being on the paranoid side, I have an AWKPATH in my
environment that doesn't include ".".  I must be really unusual in that
respect. :-P

That script or makefile should probably say "awk -f
./expand_module_aliases.awk".  Or it should set its own AWKPATH
locally.  Is a bug report desired?

Hello Ian,

David Allsopp has just fixed this AWKPATH issue in the development 
version of OCaml

Thus the issue should be definitively fixed in the next releases of OCaml.

However, I am wondering how badly is the issue affecting you? Is it just 
a matter of setting AWKPATH to an "unsafe" "." value temporarily, or you 
just cannot install recent version of OCaml until the issue is fixed?

Happy hacking, octachron.

Thanks for asking, yes I just run opam with a local AWKPATH, installed
4.09 already.  No problem.  Good to know that it's being addressed.
