pygraphviz on RedHat installation issues

[zrecommender]

I have a venv with python3.10. yum install graphviz graphviz-devel ran fine.
Approach 1: pypi
pip install pygraphviz fails on

gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -DSWIG_PYTHON_STRICT_BYTE_CHAR -I/local/home/eplamade/env-3.10/include -I/usr/local/include/python3.10 -c pygraphviz/graphviz_wrap.c -o build/temp.linux-x86_64-cpython-310/pygraphviz/graphviz_wrap.o
      In file included from /usr/include/graphviz/gvc.h:17:0,
                       from pygraphviz/graphviz_wrap.c:3021:
      /usr/include/graphviz/types.h:49:10: fatal error: cgraph.h: No such file or directory

cgraph.h is in fact present under /usr/include/graphviz.
The library seems to be under:

(env-3.10) ➜  Dev ll /usr/lib64 | grep graphviz                                                                                                                                                                                                                                                                                                    ~/Dev
drwxr-xr-x  3 root root  4.0K Apr  7 00:31 graphviz

Approach 2: Point to the verified correct folders.

cd pygraphviz
python setup.py build_ext -I/usr/include/graphviz -L/usr/lib64 -R /usr/lib64 -lgvc
pip3 install .

all successful. Then

(env-3.10) ➜  ~ python -c "import pygraphviz"                                                                                                                                                                                                                                                                                                          ~
