Hi,

Build tools installed as termux packages.

I got around issues building numpy by installing the package from it's pointless.

The other prerequisites seem to install OK by pip.

But Pandas itself fails to build.

I can see from Google that previous versions have installed OK, but can't find any confirmation of anyone having success with the latest versions (0.23.4 on 3.7).

Any ideas or pointers.

I've tried this - no luck:
LD_FLAGS=" -lm" pip3 install -vvv pandas

The other prerequisites seems to install ok
