How can I install X-Sendfile apache module so that MAMP can use it?

I have followed these instructions to install X-Sendfile, but it didn't work (it seems like it just installed it for the default apache installation). I also tried to manually copy /usr/libexec/apache2/mod_xsendfile.so to /Applications/MAMP/Library/modules/, but that produced the following error when restarting Apache:

Cannot load /Applications/MAMP/Library/modules/mod_xsendfile.so into server: cannot create object file image or add library
