You have shown us what you get with ActivePerl. When I build Crypt-Blowfish-2.10 on ActivePerl build 817, using dmake 4.7, I find no problem. However, you're output of 'dmake' differs slightly from mine. Whereas you get: 
Running Mkbootstrap for Crypt::Blowfish ()
C:\Perl\bin\perl.exe -MExtUtils::Command -e chmod 644 Blowfish.bs
dlltool --def Blowfish.def --output-exp dll.exp

I get: 
Running Mkbootstrap for Crypt::Blowfish ()
C:\Perl\bin\perl.exe -MExtUtils::Command -e chmod 644 Blowfish.bs
C:\Perl\bin\perl.exe -MExtUtils::Mksymlists \
     -e "Mksymlists('NAME'=>\"Template::Stash::XS\", 'DLBASE' => 'XS',
+ 'DL_FUNCS' => {  }, 'FUNCLIST' => [], 'IMPORTS' =
> {  }, 'DL_VARS' => []);"
dlltool --def Blowfish.def --output-exp dll.exp

You'll note that the 'perl.exe -MExtUtils::Mksymlists....' command is missing in your output.

As a first guess, try updating ExtUtils::MakeMaker to version 6.31, and see if that fixes the problem.

Cheers,
Rob
