[Bioperl-l] Can't get Bio::Tools::StandAloneBlast blastall to work in a cgi script

[hackstam]

Can anyone help me to get Bio::Tools::StandAloneBlast 
blastall to work in a cgi script.  I have a perl script with
the same code as posted below except for the cgi information
working fine.  I even was able to run the perl script in the
cgi-bin directory.  However whenever I run the code below I
alway get the following error:
-------------- WARNING ---------------------
MSG: cannot find path to blastall

method "next_result" on an undefined value at

Here is my code:

  $track->add_feature($feature);

}

print $q->header(-type=>"text/html"),
  $q->start_html(-title =>"Graph");

#print $panel->png;
print $q->end_html();

Any help is very much appreciated. Thanks!!!!!!!
