Problem installing DBD-Oracle

[VIDYASAGAR R NALLU]

Hi all,

I have problem installing DBD-Oracle. Basically i downloaded the
DBD-Oracle-1.0.6.tar.gz and uncompressed into a temporary folder. When
i'm trying to use the command "perl Makefile.pl" the following error is
displayed:
 
    Can't locate DBI.pm in @INC(@INC contains: D:Perl/lib
D:/Perl/site/lib.) at Makefile.pl line 21. BEGIN FAILED ---

provided Perl is installed at D:/Perl. What should i do now? Please help
me

Thanks in advance
