The binary might be corrupted, I think you should rebuild it.

You might want to use run-time search paths (rpaths), like so:

$ install_name_tool -change
"@executable_path/../Frameworks/Tcl.framework/Versions/8.7/Tcl"
"@rpath/../Frameworks/Tcl.framework/Versions/8.7/Tcl" /path/to/X.dylib
$ install_name_tool -change
"/Library/Frameworks/Tcl.framework/Versions/8.7/Tcl"
"@rpath/../Frameworks/Tcl.framework/Versions/8.7/Tcl" /path/to/X.dylib
$ install_name_tool -add_rpath "@loader_path" /path/to/X.dylib

You might need to do this to both X.dylib and your executable.
