Some help please with makefile

[Billy N. Patton]

I'm trying to get my makefile to work in order to convert from a cadence 
database to a gds
Here are the results of my execution
game03 % make
create /data/phy_ver10/DROP_ZONE/c014/C014.M/drc/6lm/RULE_96B5_PASS_6LM.gds
from
create /data/phy_ver10/DROP_ZONE/c014/C014.M/drc/7lm/RULE_96B5_PASS_7LM.gds
from
create /data/phy_ver10/DROP_ZONE/c014/C014.M/drc/8lm/RULE_96B5_PASS_8LM.gds
from


I would have thought the it should have list only the ones in the FILES 
variable from the rule without 6,7,8lm

From the command line I have verified the my find is working properly

find REGRESSION -follow -maxdepth 1 -name 'RULE_*' -exec basename {} \; -exec 
grep -v 'RULE_*[678]LM' {} \;
If I uncomment the rhs the 3 rules for 6lm, 7lm and 8lm work properly, 
commented they don't work
${DROP_ZONE}/%.${OUTSUFFIX} : #${CADENCEDB}/%${CADSUFFUX}

I have removed a gds file from each of the 4 directories
The report should read
create /data/phy_ver10/DROP_ZONE/c014/C014.M/drc/RULE_96B1_PASS.gds
from   /data/phy_ver10/regressionData/c014/C014.M/REGRESSION/RULE_96B1_PASS
create 6lm /data/phy_ver10/DROP_ZONE/c014/C014.M/drc/6lm/RULE_96B5_PASS_6LM.gds
from   6lm 
/data/phy_ver10/regressionData/c014/C014.M/REGRESSION/RULE_96B5_PASS_6LM
create 7lm /data/phy_ver10/DROP_ZONE/c014/C014.M/drc/7lm/RULE_96B5_PASS_7LM.gds
from   7lm 
/data/phy_ver10/regressionData/c014/C014.M/REGRESSION/RULE_96B5_PASS_7LM
create 8lm /data/phy_ver10/DROP_ZONE/c014/C014.M/drc/8lm/RULE_96B5_PASS_8LM.gds
from   8lm 
/data/phy_ver10/regressionData/c014/C014.M/REGRESSION/RULE_96B5_PASS_8LM

I know I still have more work to do to accomplish all the tasks written in the 
comments at the beginning of the makefile

FYI
my REGRESSION data base has all RULE_* flat
my DROP_ZONE his the data more structured
DROP_ZONE/6lm/RULE_*_6LM*
DROP_ZONE/7lm/RULE_*_7LM*
DROP_ZONE/8lm/RULE_*_7LM*
DROP_ZONE/RULE_*  >>>> NOT *_6LM* or *_7LM* or *_8LM*

Here is my makefile in it's entirety.  ( except the pod documentation )
