Nope, still an open issue. I also do not have any ideas left what I could try 
next.

Tried the export hints (e.g. bash profile) given in 'brew info gdal2' and 
checked with my local configuration but I do not see what the possible issue 
could be here.

Hi everyone,

the following error gives me headaches. When building my package on Travis CI 
(OS X build), I get the following error:

Building with: R CMD build

Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/Users/travis/R/Library/rgdal/libs/rgdal.so':
dlopen(/Users/travis/R/Library/rgdal/libs/rgdal.so, 6): Library not loaded: 
/Builds/unix/recipes/build/gdal-2.1.3-obj/libgdal.dylib
Referenced from: /Users/travis/R/Library/rgdal/libs/rgdal.so
Reason: image not found

it looks to me that rgdal.so is looking for libgdal.dylib in /Builds/unix/recipes/build/build/gdal02.1.3-obj

you can confirm this with the command:

otool -L /Users/travis/R/Library/rgdal/libs/rgdal.so

it will list where it's expecting to find libgdal.dylib

my guess is that the root of the issue is that the libgdal.dylib that rgdal.so linked against, thinks that it lives at /Builds/unix/recipes/build/build/gdal02.1.3-obj

you can confirm this with:

otool -L /Builds/unix/recipes/build/gdal-2.1.3-obj/libgdal.dylib

you can change where .so's and .dylibs think they live, and where they think their dependencies live with the install_name_tool tool.

i can walk you through this off-list if you need.

cheers
