i added some debug statements to the script, which indicated that 
startlam.sh generated this statement:

 -catch_rsh /opt/sge/default/spool/qcn11/active_jobs/59.1/pe_hostfile 

whereas the rsh wrapper generated this (note additional lines not included 

 /opt/sge/bin/lx24-amd64/qrsh -V -inherit -n -p 32796 qcn11 exec 

the former (startlam.sh) comes from the script line:

 # useful to control parameters passed to us  
 echo $*

that seems fine.
the latter line (rsh wrapper) comes from the line:

 echo $SGE_ROOT/bin/$ARC/qrsh -V -inherit $rhost $cmd
 exec $SGE_ROOT/bin/$ARC/qrsh -V -inherit $rhost $cmd

this is triggered by the condition $minus_n != 1.

i'm perplexed as to how..

 $rhost $cmd

expands to..

 -n -p 32795 qcn15 exec '/opt/sge/utilbin/lx24-amd64/qrsh_starter'
