It seems missing ipopt library, can you post the info of brew search ipopt? – delta

ipopt library is missing. Try

then run pip install ipopt again.

i'm not sure if it's too late, but you can try here

git clone https://github.com/coin-or/Ipopt
make
make test
make install

that includes the missing files Ipopt/src/Interfaces/IpIpStdCInterface.h that you mentioned before
