What is this specialclass thing?

You have the syntax wrong. PrepModule(HostMatch,ginseng g3_node) works
for me.

$ hostname
belmont.cs.uchicago.edu
$ cat ~/.cfagent/modules/HostMatch 
#!/usr/bin/perl
if ( `hostname` =~ /$ARGV[0]/ ) { print "+$ARGV[1]\n"; }
$ cat test.cf 
#!/usr/sbin/cfagent --no-splay --inform --no-lock --file
groups: g3_node_bugus = ( PrepModule(HostMatch,belmont g3_node) )
control: actionsequence = ( shellcommands )
shellcommands: g3_node:: "/bin/echo g3_node is defined"
# end test.cf
$ ./test.cf 
cfengine:: Executing script /bin/echo g3_node is 
defined...(timeout=0,uid=-1,gid=-1)
cfengine::/bin/echo g3_no: g3_node is defined
cfengine:: Finished script /bin/echo g3_node is defined
$ 

Example was 2.1.3 running on Debian stable.

If that works for you, that's cool.
