Oscillator problems

[RUBiksCUbe]

I'm using an 18F252 with a 10 MHz external resonator and I can't figure out the code needed to tell the pic to run in what the datasheet called "HS" mode. I'm new to the PIC and PicBasic, but I think that I have my PIC set up correctly (pin 1 tied high w/ 4.7K resistor) and I have a good downloader. Here is the code that I have been trying:

DEFINE OSC 10
loop:
high PORTB.0
low PORTB.1
pause 500
high PORTB.1
low PORTB.0
goto loop
end

but I cant get any sign of life out of my PIC

Presetting Configuration Fuses (PIC Defines) into your Program

Maybe it's alive and you just can't see it.

You outputs will only change for a fraction of a uSec every half second.

Try adding another "pause 500" before the "goto loop".

I just added the PIC defines into my program, and eliminated the "Overwriting previous adress" error by commenting out the __CONFIG commands (not the INCLUDE command though) in the 18F252.inc file, but I still have 4 errors remaining that I dont understand.
Duplicate label ("DDRA")
Duplicate label ("DDRB")
Duplicate label ("DDRC")
Superseeding current maximum RAM and RAM map.

EDIT:

If I comment out the INCLUDE line of 18F252.inc then I get different errors:
Duplicate Label ("_PORTL")
Duplicate Label ("_PORTH")
Duplicate Label ("_TRISL")
Duplicate Label ("_TRISH")
