>Description:
cups build fails on a link error due to missing krb5 libraries.

print/cups is parameterized as follows:
These options are enabled by default:
        dbus dnssd kerberos libusb

These options are currently enabled:
        dnssd kerberos libusb

the compilation error message is:
ld: cannot find -lgssapi_krb5
ld: cannot find -lk5crypto

the content of /usr/pkgsrc/print/cups/work/.buildlink/lib does not contain any link to 'gssapi_krb5' of 'k5crypto' library. The build process detects USE_BUILTIN.heimdal=yes but neither /usr/lib/libgssapi_krb5*.so nor /usr/lib/libk5crypto*.so exist.
>How-To-Repeat:
Build print/cups with kerberos support and builtin heimdal
>Fix:
