bad.
This is all?
If so you have a mingw perl dll here, which cannot be loaded by cygwin perl.

mine:
$ ldd /usr/lib/perl5/site_perl/5.10/i686-cygwin/auto/Class/XSAccessor/XSAccessor.dll
        ntdll.dll => /cygdrive/c/Windows/SYSTEM32/ntdll.dll (0x77990000)

        KERNELBASE.dll => /cygdrive/c/Windows/system32/KERNELBASE.dll
(0x75b90000)
        cygwin1.dll => /usr/bin/cygwin1.dll (0x61000000)
        ADVAPI32.DLL => /cygdrive/c/Windows/system32/ADVAPI32.DLL (0x76e20000)
        msvcrt.dll => /cygdrive/c/Windows/system32/msvcrt.dll (0x75de0000)
        sechost.dll => /cygdrive/c/Windows/SYSTEM32/sechost.dll (0x76190000)

        cyggcc_s-1.dll => /usr/bin/cyggcc_s-1.dll (0x67f00000)
        cygperl5_10.dll => /usr/bin/cygperl5_10.dll (0x56010000)
        cygcrypt-0.dll => /usr/bin/cygcrypt-0.dll (0x72fe0000)
        cygssp-0.dll => /usr/bin/cygssp-0.dll (0x67280000)
