Comment (by TP75):

 The following **workaround** compiles without error.

 Refering to https://bugs.squid-cache.org/show_bug.cgi?id=4903#c5
 > For now you can probably work around this by using LDFLAGS in your build
 options, like so:
 >   ./configure LDFLAGS="-lresolv"

 Adding the **configure.ldflags-append "-lresolv"** parameter to the
 kerberos variant section in the squid4 Portfile helps.

 Thanks for the support.  One may refer to the MacPorts Guide
 [https://guide.macports.org/#reference.phases.configure 5.3.7. Configure
 Phase Keywords] and [https://guide.macports.org/#development.local-
 repositories 4.6. Local Portfile Repositories] for learning how to apply
 these changes locally.
