mango linking question

[Langer, Stephen A. (Fed)]

Hi --

What do these messages mean, and do I need to worry about them?  They occur when linking a program with clang++.

% /usr/bin/clang++ -L/opt/local/lib ... something.o ... -lpangocairo-1.0 -lpango-1.0 ... -o something.so

ld: warning: dylib (/opt/local/lib/libpangocairo-1.0.dylib) was built for newer macOS version (11.2) than being linked (11.0)
ld: warning: dylib (/opt/local/lib/libpango-1.0.dylib) was built for newer macOS version (11.2) than being linked (11.0)

I'm using Big Sur 11.6 with Xcode 13.0.  Macports is up to date, and so is pango.

% port installed pango
The following ports are currently installed:
  pango @1.42.4_3+quartz+x11 (active)

Thanks.
