No, the perl pieces are only needed to build OpenSSL, afterwards they 
don't have any role.  It's getting picked up only because Strawberry 
comes bundled with it, and it's earlier, or the only one, on your PATH.

After you install git and other things there are multiple copies of a 
few libs and apps wandering around in your filesystem.  In my VM used 
for CI it's an openssl.exe that comes with mingw that gets picked up first.

He has an openssl.cnf that works for certificate creation in 
/mingw64/ssl/openssl.cnf, which I attach, you should be able to create 
C:/Strawberry/c/ssl and see what happens if you drop it in there.
