Oops prevention: is there an easy way to detect if the compilers are disabled?

Here's the scenario:

Regeneration of an environment for an application.

Files get regenerated with structure changes, RPG programs get regenerated over the restructured files. All under the automated control of an environment modification and regeneration utility.

But for some reason, the customer has an expired license on their development tools, and some poor schmuck didn't think about that before doing a regen.

Thankfully, when this actually happened, it was on a test environment, rather than the live one; if it had been the latter, they'd probably not be happy campers.

Given that scenario, is there any way for this environment modification and regeneration utility to check to make sure the compilers are available before it allows regeneration (or any changes requiring regeneration)?
