RHEL 9.4 does not have the PKG_CONFIG_PATH environment variable configured even though pkg-config is installed. Therefore, cargo cannot build pango-sys because the pango.pc file is needed. Setting the PKG_CONFIG_PATH environment variable to /usr/lib64/pkgconfig still does not work, even though pango.pc file is in that directory.
PKG_CONFIG_PATH environment variable was to /usr/lib64/pkgconfig because the pango.pc file is in that directory. However, cargo run still says that it cannot find the pango.pc file, even though it now recognizes the PKG_CONFIG_PATH environment variable is pointed to the correct location.

The system library `pango` required by crate `pango-sys` was not found.
The file `pango.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
PKG_CONFIG_PATH contains the following:
-
- /usr/lib64/pkgconfig
HINT: you may need to install a package such as pango, pango-dev or pango-devel.
