macOS Catalina support

[rcorrear]

Hi!

I'm trying to get this running on macOS Catalina (which only supports 64 bit apps) and I'm running into the following issue:

$ createClient -D -t pharo64 pharoClient -v Pharo7.0
...
The 32-bit libraries required by Pharo have not been installed on this system. :: downloadSmalltalkClient -v Pharo7.0 -d /Users/ricardocorrea/Projects/smalltalk/GsDevKit_home/dev/clients/pharoClient
Error on or near line 121 :: createPharoTodeClient -c -t 64 -D -v Pharo7.0 pharoClient :: createPharoTodeClient -c -t 64 -D -v Pharo7.0 pharoClient
Error on or near line 109 :: createClient -t 64 -c -D -v Pharo7.0 pharoClient :: createClient -t 64 -c -D -v Pharo7.0 pharoClient
Error on or near line 164 :: createClient -D -t pharo64 pharoClient -v Pharo7.0 :: createClient -D -t pharo64 pharoClient -v Pharo7.0

Tried other versions as well without success.

I've also tried downloading Pharo 64 bit (a little change in createClient is needed (add /64/ to the URL) and that gives me:

$ createStone devKit_351 3.5.1 |& tee -a $GS_HOME/install.log
...
This interpreter (vers. 68021) cannot read image file (vers. 6505).

Which I believe means the image is 32 bit and the VM 64 bit, but I'm definitely not wise enough to create my own image.

Is this a supported configuration and if not are there plans? Can I help?
