This isn't really a huge issue, because you're obviously supposed to have the required dependencies to utilize a mod, but the user has no way to know that they didn't include them since there is no mention of that in the logs.
Forge currently doesn't have a gui to show missing dependencies (as far as I'm aware) and uses the log.
Instead, the log will simply stop because of Quartz failing at startup, so no mention of the required dependencies.

To replicate:

• include quartz, phosphophyllite and any mod that requires some sort of library (e.g. Ars Nouveau)
• do not add that required library or disable it by adding .disabled after the .jar extension of the file

Result:
latest.log
