[gradsusr] dyld: Library not loaded: /Users/jma/grads/supplibs/lib/libpng15.15.dylib

Hi,

I am using GrADS 2.2.1 on OSX 11 and  have experienced same problem.
My solution was modifying paths of libraries one by one for a grads executable.
I  cannot sure this works in your environment but hope it helps.

export PATH_SUPPLIBS="your supplibs-builds directory"
install_name_tool -change /Users/jma/grads/supplibs/lib/libncurses.5.dylib ${PATH_SUPPLIBS}/lib/libncurses.5.dylib ./grads-2.2.1/bin/grads
install_name_tool -change /Users/jma/grads/supplibs/lib/libpng15.15.dylib ${PATH_SUPPLIBS}/lib/libpng15.15.dylib ./grads-2.2.1/bin/grads
install_name_tool -change /Users/jma/grads/supplibs/lib/libz.1.dylib /usr/lib/libz.1.dylib ./grads-2.2.1/bin/grads
install_name_tool -change /Users/jma/grads/supplibs/lib/libhdf5.101.dylib ${PATH_SUPPLIBS}/lib/libhdf5.101.dylib ./grads-2.2.1/bin/grads
install_name_tool -change /Users/jma/grads/supplibs/lib/libnetcdf.7.dylib ${PATH_SUPPLIBS}/lib/libnetcdf.7.dylib ./grads-2.2.1/bin/grads
install_name_tool -change /Users/jma/grads/supplibs/lib/libhdf5_hl.100.dylib ${PATH_SUPPLIBS}/lib/libhdf5_hl.100.dylib ./grads-2.2.1/bin/grads
install_name_tool -change /Users/jma/grads/supplibs/lib/libcurl.4.dylib ${PATH_SUPPLIBS}/lib/libcurl.4.dylib ./grads-2.2.1/bin/grads
install_name_tool -change /Users/jma/grads/supplibs/lib/libtiff.3.dylib ${PATH_SUPPLIBS}/lib/libtiff.3.dylib ./grads-2.2.1/bin/grads

Best regards,
Jonghun
