unable to install hplip-3.12.4.run - linux mint 13

Hello - hoping to fix a scanning problem w/ Linux Mint 13.

1. Your Linux Distribution and version - Linux Mint 13
2. Your printer make/model - HP c7280 all-in-one
3. If possible, run 'hp-check -t' and post the output - unable to run
4. A detailed explanation of your problem - (see below)
5. Steps to recreate the problem - (see below)

Ive managed to install the printer successfully via the Mint GUI and am able to print w/out trouble but the os does not recognize the scanner as available (from Simple Scan: 'No scanners detected'). Oddly enough Mint 11 recognized both the printer and the scanner functions and worked fine. In attempting to correct the prob the HP site directed me to 'http://hplipopensource.com/hplip-web/index.html' as a source for Linux drivers. Attempting to install HPLIP I receive the following message:

warning: Missing REQUIRED dependency: gcc (gcc - GNU Project C and C++ Compiler)
warning: This installer cannot install 'gcc' for your distro/OS and/or version.

I checked the package manager and found that I do in fact have the 'gcc' dependency installed. Uninstalled and reinstalled it w/ the same results.

Thoughts?

Many thanks for the assist.
