We don't have cups-devel installed on our production system and therefore don't have libcups.so, but only libcups.so.2.

Therefore using ffi-cups fails with LoadError: Could not open library 'cups': cups: cannot open shared object file: No such file or directory. Could not open library 'libcups.so': libcups.so: cannot open shared object file: No such file or directory.

Giving the full filename via ENV['CUPS_LIB'] (as implemented in ffi-cups.rb) does not work, because ffi-cups/ffi/array.rb, ffi-cups/ffi/cups.rb and ffi-cups/ffi/http.rb don't honor the value from ENV, but always use ffi_lib('cups').

In lib/ffi-cups/printer.rb:60: last_error = Cups.cupsLastErrorString().

I guess that should be FFI::Cups.cupsLastErrorString().
