Error: Processing of port mariadb-10.1 failed

mariadb-10.9 has no issues, however I needed 10.1 to access an older MariaDB server.

Any help is much appreciated!

The error in the log is actually:

mariadb-10.1.48/version:1:1: error: expected unqualified-id
MYSQL_VERSION_MAJOR=10
^

This is an incompatibility between this project and C++20-capable compilers on case-insensitive filesystems. This project's VERSION file is being misinterpreted as the C++ <version> header. Solutions that the port could employ include not adding an -I flag that points to the directory that contains the VERSION file, or deleting or renaming the VERSION file and updating any essential references to it elsewhere in the project.
