idhash.c:1:10: fatal error: 'bignum.c' file not found when using v 0.1.1.1 and 0.1.1.2

[MFRWDesign]

Came across this bug today while trying to bundle install our project. Posting this issue in case it's of some help to someone else. I tried to track it down but couldn't find anything that helped (including brew reinstall vips, brew upgrade && brew update.

Eventually I fixed the bundling error for dhash-vips by rolling the version specified in the Gemfile back to '0.1.1'.

I'm running:
OS X 10.15.5
Homebrew 2.5.1
Ruby 2.7.1 (via rbenv v1.1.2)

(I suspect the problem to have arisen from the changes to extconf.rb in this commit: http://github.com/Nakilon/dhash-vips/commit/56fba57aac82552f26086474cd57b63a4a99dc36%20 but I can't be sure as I wasn't able to verify any fix.)

Hi
Same problem with 0.1.1.2 and 0.1.1.1. Works fine on 0.1.1

current directory: /Users/yarik/.rbenv/versions/2.6.5/lib/ruby/gems/2.6.0/gems/dhash-vips-0.1.1.2
make "DESTDIR=" clean

current directory: /Users/yarik/.rbenv/versions/2.6.5/lib/ruby/gems/2.6.0/gems/dhash-vips-0.1.1.2
make "DESTDIR="
compiling idhash.c
idhash.c:1:10: fatal error: 'bignum.c' file not found
#include <bignum.c>
         ^~~~~~~~~~

make: *** [idhash.o] Error 1

Thank you guys for the bug report!
Probably I should make some Github Action to test the installation process.

bignum.c is a part of Ruby source code that is needed for compilation if you want the fingerprint comparison to be 15 times faster. Essentially the 'bignum.c' file not found means that you didn't use flag -k in rbenv install. Did you?
It should be handled and just skip the compilation of the native extension though. Maybe in last releases I broke it and forgot to check.

@MFRWDesign @ynelin please, check if 0.1.1.3 works for you and I'll yank 0.1.1.2, 0.1.1.1.
