Problem with Compiling

I tried to do a really simple blink led, but my code won't compile!
Every time I try to compile:

@ DEVICE PIC16F877A, HS_OSC, WDT_OFF, PROTECT_OFF, LVP_OFF
DEFINE OSC 20
LED VAR PORTB.2

TRISB=%00000000
PORTB=%00000000

main:
low LED
pause 1000
high LED
pause 1000
goto main
END

I get an error message that says I have an undefined symbol 'pic16f877a'
What can I do to fix this?

Which version of PBP are you using? 2.??
For that matter, did you try simply really hard to read the green manual?

Are you using MPASM or PM as your assembler?
