PK51 is the toolset for the 8051 which is not compatible with ARM.  
You need the DK-ARM tools which include uVision3.  You can actually 
download a fully-functional toolset from www.keil.com.  The Keil 
Compiler, Assembler, and Linker are included and are fully 
functional.  The GNU tools are also available for download and they 
are unrestricted as well.  The only limitation (at this time) is that 
the debugger is limited to 16K program size.
