7bb8eb0bc352b47ee962283898f9becbb4f36c62 script install_db4.sh added check for patch command (Nathan Garabedian)
Pull request description:
First contribution. I've read the CONTRIBUTING guide and hope I'm doing this correctly, but please kindly point out anything I should do differently.
I found while running the contrib/install_db4.sh patch that it would fail suddenly with "patch: command not found". I'd rather see it fail early before doing any work, allow me to install the `patch` command, and then run again. (CentOS Linux) Here's a PR proposed to fix it.
error message:
