Yes.  That's what is happenning.  The default PATH of cron jobs doesn't
include `/usr/local/bin', but you have lots of options:

  1) Add it to the crontab file

        PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin"

        crontab entries here

  2) Modify the default path in your Perl script:

        $ENV{PATH} = '/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin';

        my $scomd = join(' ', ('/usr/local/bin/ps2pdf',
             '-dPDFSETTINGS=/prepress',
             '-dProcessColorModel=/DeviceGray',
             '-dAutoRotatePages=/PageByPage',
             '-dDownsampleMonoImages=true',
             '-dMonoImageDownsampleType=/Average',
             '-dMonoImageDownsampleThreshold=1.5',
             '-dMonoImageResolution=600'
             $inpath.$cur_ps_files[0],
             $outpath.$pdffilename));

        system($scomd) == 0 or return "system $scomd failed: $?";
