Problem starting gimp

[Gregory Bonar]

I just installed Macports 2.5.3.
When I try to start gimp I get the following messages:

dyld: Library not loaded: /opt/local/lib/libpng14.14.dylib

  Referenced from: /opt/local/bin/gimp

  Reason: image not found

Abort trap: 6

I'm new to Macports.
I just typed 'gimp' on the command line.
Can you tell me the correct way to start gimp?
MacOS 10.13.6
Thanks
