Tested locally against all global-ocean configs, and there are no more sneaky INCLUDES or env variables I can see. I think this is enough for me to approve the merge, although we probably want to retry teh build in sith before handing it over for PS47.

I have built a wheel and installed it as 0.6.5rc1 on mobbs-59 on exab and excd. The failed daily tests are now back to life.

[twsearle]

I have run the default sith tests, so hopefully that should be using mobbs-59 in the following:

Testing

• exab_ostia configuration
• exab_ocnd configuration
• exab_gl_ocn configuration
• exab_gulf configuration
• exab_amm7 configuration
• exab_amm15 configuration
• excd_ostia configuration
• excd_ocnd configuration
• excd_gl_ocn configuration
• excd_gulf configuration
• excd_amm7 configuration
• excd_amm15 configuration

all looks good to me - even the OSTIA one that was failing in monitoring last Ichecked.
