I included the cygcheck output. The error I get is:

Can't load 
'/usr/lib/perl5/5.14/i686-cygwin-threads-64int/auto/IO/IO.dll' for 
module IO: No such process at /usr/lib/perl5/5.14/XSLoader.pm line 71.

The output on IO.dll dependencies is:

$ cygcheck /usr/lib/perl5/5.14/i686-cygwin-threads-64int/auto/IO/IO.dll
C:\rhcygwin\lib\perl5\5.14\i686-cygwin-threads-64int\auto\IO\IO.dll
   C:\rhcygwin\bin\cygwin1.dll
     C:\WINDOWS\system32\KERNEL32.dll
       C:\WINDOWS\system32\ntdll.dll
   C:\rhcygwin\bin\cygperl5_14.dll
     C:\rhcygwin\bin\cygcrypt-0.dll
     C:\rhcygwin\bin\cyggcc_s-1.dll
     C:\rhcygwin\bin\cygssp-0.dll

As you can see in the attachment, I use the previous version of Red 
Hat's Cygwin. After downgrading perl everything works fine again.

Thanks,
Daniel
