libproj.13.dylib problem

[Martin Sluka]

I use MacOSX 10.13.6

I installed Survex by help of brew without any problem. 

But to check it I tried just do “cavern" in terminal

It generated next error:

Last login: Wed May  8 21:30:57 on ttys000
StudioSka3siMac:~ studiosluka_3$ cavern
dyld: Library not loaded: /usr/local/opt/proj/lib/libproj.13.dylib
  Referenced from: /usr/local/bin/cavern
  Reason: image not found
Abort trap: 6
StudioSka3siMac:~ studiosluka_3$ 

In my system, there is version 15 in that place: /usr/local/opt/proj/lib/libproj.15.dylib

May you help me?

Thanks

Martin
