Makefile.PL help

[Billy N. Patton]

Here is my Makefile.PL:
use ExtUtils::MakeMaker;
my $HTYPE = `uname`;
chomp $HTYPE;
WriteMakefile(
  'NAME'            =>  'Laff'
 ,'PREFIX'          =>  './'
 ,'VERSION_FROM'    =>  'Laff.pm'
 ,'LIBS'            =>  [" -Llibcdmg/${HTYPE} -lcdmg " , ' -lm ']
 ,'OPTIMIZE'        =>   '-g3'
 ,'DISTNAME'        =>  'LaffPerl'
 ,'VERSION'         =>  '1.0'
 ,'INSTALLDIRS'     =>  'perl'
 ,'INC'             => '-Ilibcdmg'
 ,'LDFROM'          => '$(OBJECT) libcdmg/${HTYPE}/libcdmg.a',
);
sub MY::subdirs {
'
$(OBJECT) : libcdmg/${HTYPE}/libcdmg.a
libcdmg/${HTYPE}/libcdmg.a : FORCE
        cd libcdmg ; /usr/local/bin/make
test :: ctest
ctest:
        cd libcdmg ; /usr/local/bin/make  test
clean ::
        cd libcdmg ; /usr/local/bin/make clean
'
}
When I run Make everything is ok until I get to:
rm -f blib/arch/auto/Laff/Laff.so
LD_RUN_PATH="/usr/lib" gcc  -G -L/apps/perl/5.8.0/lib 
-R/apps/perl/5.8.0/lib Laff.o libcdmg//libcdmg.a  -o 
blib/arch/auto/Laff/Laff.so   -lm
gcc: libcdmg//libcdmg.a: No such file or directory
             ^
             |
             |
The ${HTYPE} seems to be missing from either the LDFROM or LIBS keys
