compiler-libs.3.12.1: Sys_error("/home/djs/.opam/system/build/compiler-libs.3.12.1/parsing/asttypes.mlimods: No such file or directory")

[djs55]

I do a:

<download and reinstall opam 0.6.0>
rm -rf .opam
opam init
opam install utop

and then it fails compiling compiler-libs-3.12.1:

Due to some errors while processing compiler-libs.3.12.1, the following actions will NOT be proceeded:
 - install utop.1.2.1
[ERROR] while installing compiler-libs.3.12.1
  Sys_error("/home/djs/.opam/system/build/compiler-libs.3.12.1/parsing/asttypes.mlimods: No such file or directory")

I'll play with it a bit more to see if I can understand what's happening.
