[opam-devel] opam getting compiler version wrong

[Ashish Agarwal]

I'm trying the option of doing `opam-admin upgrade-format`, but what's the
best way to get `opam-admin`? Is it by chance available as a pre-compiled
binary like `opam` is?

I'm trying to compile opam myself, but getting this:

ocamlfind ocamlc -package
unix,bigarray,extlib,re,re.str,re.pcre,re.glob,cmdliner,ocamlgraph,cudf,dose3.common,dose3.algo,jsonm,no
-c -g -w +a-4-44-48 -bin-annot -short-paths -safe-string -I core -I format
-I solver -I repository -I state -I client -I core/ core/opamCompat.mli
ocamlfind: Package `no' not found

Unfortunately "no" isn't very easy to search for. Is that really the name
of an ocamlfind package?
