I have been trying to install the BerkeleyDB CPAN module on my Windows 7 (x86_64) PC without any luck (BerkeleyDB::Hash is what I need). I have 64 bit ActivePerl and Oracle Berkeley DB 11gR2 5.3.15 installed. First I tried installing using the command :

cpan install BerkeleyDB

This came back with the error:

It looks like the installation of dmake and MinGW has failed.  You wil
+l not be
able to run Makefile commands or compile C extension code.  Please che
+ck your
internet connection and your proxy settings!

So I installed Microsoft Windows SDK for Windows 7 and .NET Framework 4. Then I installed cpanm cpan App::cpanminus And when I tried running: 
cpanm BerkeleyDB<code>

I got the error:

<code>Note (probably harmless): No library found for -llibdb
Note (probably harmless): No library found for bufferoverflowU.lib

[download]
So I edited the config.in file and changed the lib and include paths to: 
INCLUDE    =  C:\PROGRA~2\Oracle\BERKEL~1.15\include
LIB =  C:\PROGRA~2\Oracle\BERKEL~1.15\lib

Now when I ran perl makefile.pl, the warning about -llibdb went away. When I tried running: nmake I got errors:

I've nearly lost all hope of ever building this module successfully on my PC. Has anyone been lucky with this? Many thanks, SN
