First run cpanp -i Devel::PPPort

then from within BeginLift directory run  perl -MDevel::PPPort -e Devel::PPPort::WriteFile();

then run  perl ppport.h --patch=the.patch

then run  patch < the.patch

then run  make realclean then  perl Makefile.PL && make

When I tried this I got

$ perl ppport.h --patch=the.patch

The warning had me curious, so the next thing I check is

$ objdump -p C:\perl\5.14.1\bin\MSWin32-x86-multi-thread\perl514.dll |

Hmm, doesn't look good, so I grep the source http://perl5.git.perl.org/perl.git?a=search&h=HEAD&st=grep&s=pad_swipe and see

embed.h
