cannot install required openMP on macOS

[kuriwaki]

Do you have any recommendations for installing OpenMP? I cannot install your package because of it.

I know this is not a problem with your package specifically. I tried for example this modification of Makevars from the data.table doc but that gave me the same error.

@kuriwaki Good point. I removed all the flags related to OpenMP which were not necessary in the first place. Could you try installing the package again?

works fine now! Thanks a lot.
