raccheck: Error RC-001 - Unable to read driver files.

I just downloaded the latest raccheck.
Got the following error when I tried to run raccheck:
qsst1f001db01:/oracle/product/raccheck>$ ./raccheck -a
-bash: ./raccheck: /bin/env: bad interpreter: No such file or directory

After I changed the first line from #!/bin/env bash to #!/bin/bash, then got the following error:

qsst1f001db01:/oracle/product/raccheck>$ ./raccheck -a
./raccheck: line 9721: [: -eq: unary operator expected
./raccheck: line 9724: [: -eq: unary operator expected
./raccheck: line 9727: [: -eq: unary operator expected

Error RC-001 - Unable to read driver files. Please report this error to your Oracle representative for action.
