It looks to me like your remote system (sirius) is having trouble locating
the PVM daemon script file.  I had some very similar problems; let me give
you some background and describe what ultimately worked for us.

I spent about a month trying to get PVM to work on our network of RS/6000
workstations.  The RS/6000 operating system (AIX) defaults to the K-shell
(ksh) and does not use ".login" or ".cshrc" files; it uses ".profile" and
".kshrc" instead.  This causes some difficulties, but these can be resolved
with PVM 3.3.2 by setting an environment variable called PVM_DPATH, which
points to the location of the PVM daemon script file ($PVM_ROOT/lib/pvmd).

I put the following definitions in my ".profile" file, and things seem to
work fine now:

	export PVM_ROOT=/afs/cc.lehigh.edu/home/fc03/public/pvm3
	export PVM_DPATH=$PVM_ROOT/lib/pvmd
	export PVM_ARCH=RS6K

You can make whatever modifications are necessary for your site.  Once
PVM_ROOT is set correctly for your site, it should not be necessary to
change the definition of PVM_DPATH.


I hope this helps,
