[MITgcm-support] Installation of gfortran and netcdf

[Dr Nick Rogan]

Thanks Dimitris,

I'll keep this all in mind. I've finally managed to get Macports 
installed and another respondent has given me some step by step 
installations steps using that to go through. Hopefully, that will work. 
I saw the info RE Yosemite yesterday, unfortunately I don't have a 
backup drive and the laptop is actually my girlfriends, so can't risk 
her documents/work to upgrade. This short term post was ideal for me at 
first, but it's severely limited when it comes to technical support and 
financial backing!

Thanks for your help.

Nick
