[Proj] Failed to initialize PROJ.4 with "..."

If it's not working with any transform could be a library or library
dependency not present or not found. Or using a 32bit instead of 64bit
library or visa versa.

On Windows you can use Dependency Walker and sysInternals Process Monitor to
debug the problem machine. On Linux maybe strace can help?
