Installing LoopTools 2.12 on Mac OS X 10.10.3

./configure

the following waring appears

do we have MathLink... no

and the installation does not work properly. (My friend says his installation was successful if his Mathematica Kernel was running. It didn't work for me.)

Following this Japanese instruction, I copied all the files in

/Applications/Mathematica.app/Contents/SystemFiles/Links/MathLink/DeveloperKit/MacOSX-x86-64/CompilerAdditions/

into

.../LoopTools-2.12/src/tools/

by replacing all the files with the same name.

Then I followed the installation instruction of the looptools.
It works!
