[Bioperl-l] blast/cgi question

[Huizhuan Wu]

Hi,
  I am new to Bioperl. Now I need to work on a website
that accepts a sequence from users and then a BioPerl script blast it
against a local db and prints out the result. The problem is my BioPerl
cgi script works fine locally (I set the params through commandline) but
doesn't work through web(error msg: blastall call crashed...). Do you
happen to know how to solve this?
    regards,
    Sophia
