Running "m4 --version" alone appears to execute the one in /usr/bin (1.4.4), while executing under strace seems to run the correct one in /usr/local/bin (1.4.5).

Probably your shell has cached the location of the previously installed M4. Run 'hash -r' or equivalent at the command line to make it actually look in the path
