Error with Custom Component Creating A Package

[GreenMeanieOz]

I have used TJvCustomLED to create a new component.
Testing the component by creating it at runtime works how I expected it to.
When I try compiling it in a package I get the following errors:

[dcc32 Fatal Error] Jcl.dpk(37): E2225 Never-build package 'rtl' must be recompiled

[dcc32 Fatal Error] sdwEngineComponents.dpk(40): E2202 Required package 'Jcl' not found

I'm an amateur and this is the first time I have used a 3rd party custom component other than the standard TCustomControl.
I'm poking around in the dark.

Thank-you
