I always have trouble with cpan!
This time I tried to install Math::FFT, and it died with this error message: 

dlltool --def FFT.def --output-exp dll.exp
'dlltool' is not recognized as an internal or external command, operable program or batch file.
dmake.exe:  Error code 129, while making 'blib\arch\auto\Math\FFT\FFT.dll'
  RKOBES/Math-FFT-1.28.tar.gz
C:\Perl\site\bin\dmake.exe -- NOT OK    
CPAN: YAML::XS loaded ok (v0.35)
Running make test
  Can't test without successful make
Running make install
  Make had returned bad status, install seems impossible
The file C:\Perl\site\bin\dmake.exe DOES exist ,24kb, dated 10/3/2011.

What or where is dlltool, which it can't find?
How can I find what is wrong with these files or get proper versions?
Or, is there some other command to use other than cpan?
I have something called cpanplus, but the system doesn't recognize it and I can't find an executable,



If anyone should be interested, here is the entire cpan screendump:
