Hi Alistair,
I'm loading via the Gofer commands that I found here:
http://pharo.gemtalksystems.com/book/PharoTools/OSProcess/
Is that what fails for you?
Loading it in to Pharo 6 instead of Pharo 7 works :-)

I'm not seeing the problems you mention below (using my locally built
VM):

$ pharo --version

Thierry, thanks for letting me know about the re-write, I'll look in to
that next.

Cheers,
Alistair

I wanted to try and reproduce this with my locally built VM but can't
    even load OSProcess because it is using the deprecated message
    #ifNotNilDo:.
I'm currently loading OSProcess using:
Metacello new
            configuration: 'OSProcess';
            version: #stable;
            repository: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo50/
    main';
            load.
Would you please let me know how you load OSProcess?
Thanks,
    Alistair
