This error message is coming from an attempt to run the podchecker program 
that normally comes with your Perl installation, in order to create the 
documentation for the Perl Channel Access interface.  That interface doesn't 
actually build properly for the Cygwin or Windows target architectures anyway, 
although on my installation it is possible to build the documentation so I 
didn't disable that part of the build.

The particular error message you're getting implies that your Perl interpreter 
is not found at the /usr/bin/perl location where the podchecker installation 
thought it should be.  When you're building the cygwin-x86 host architecture 
of EPICS Base you really do need to use the Cygwin version of Perl; other Perl 
versions won't understand the /cygdrive/x paths that Cygwin uses.

However the Perl CA interface in src/cap5 is optional, and that directory 
comes at the end of the direcory list so you can just ignore this error and 
assume that your build of EPICS base has completed normally.

HTH,
