PCL on HP and Mac

[2ELETBONARIN@IPMCC2.POLIMI.IT]

We are trying to install PCL on HP 9000-300 with HP Common LIsp 2.01, but
the files contained in the distribution kit seems not to be OK. The WALK file
does not contain the definition for ENVIRONMENT-MACRO with the HP compiler
option. Can anyone help me?
 WE are trying also to install PCL on a MacII with Allegro, but we have problems
when methods are called, obtaining an error related with a method call with
NIL arguments. Is it T that PCL runs with Allegro. Has anyone exerienced it?
   Thank you, Andrea Bonarini
