dbi not installing

Do i have to be in a particular directory to install dbi?
I have ActiveState and followed the manual ...

ppm install DBI


then ran x.cgi, but error reported :

Software error:
Can't locate DBI.pm in @INC (@INC contains: C:/Perl/lib
C:/Perl/site/lib .) at c:\PROGRA~1\EASYPH~1\cgi-bin\x.cgi line 4.


my code is correct i think...
#!C:/Perl/bin/perl
use CGI::Carp "fatalsToBrowser";
use DBI;
print "Content-Type: text/html\n\n";
print "Done.";

any ideas?
