hgdl kernel to work with healpix routines

I can call >>hgdl in terminal and use healpix idl routines along with gdl routines. But, I cannot use healpix idl routines in jupyter gdl kernel. How can I modify the setup to create an hgdl kernel? I tried replacing gdl->hgdl, GDL->HGDL and idl->hidl and then run python3 setup.py install --prefix=~/.local. But this does not work.
