building gcc48 is not supported with Xcode 9 or greater

[PWLisowski]

Both HomeBank and pgplot require gcc48 and it is apparently not supported with Xcode 9 or treated (I am running Xcode 11.2).

partial log:

Error: building gcc48 is not supported with Xcode 9 or greater
Error: Failed to fetch gcc48: unsupported platform

and

Description:          The PGPLOT Graphics Subroutine Library is a Fortran- or
                      C-callable, device-independent graphics package for making
                      simple scientific graphs. It is intended for making
                      graphical images of publication quality with minimum
                      effort on the part of the user. For most applications, the
                      program can be device-independent, and the output can be
                      directed to the appropriate device at run time.

so maybe we can figure out how to get you up and running. Do you already have these installed? Please show us the results of:

port -v installed homebank
port -v installed pgplot

You could reinstall whatever ports you have installed with +gcc48 with a newer gcc variant. E.g.

sudo port install pgplot -gcc48 +gcc9

But if you have ports installed with +gcc48 in the first place, that implies that they were built on an older OS version and you need to follow the wiki:Migration procedure.
