A few days ago, one of updated ports would not install (gpgme ? ), citing a conflict but suggesting the use of 
force-install. I (foolishly?) forced the install, but wasn’t too worried as Kmymoney continued to function. However, after the latest update it is broken.

I’m not sure what to do, don’t want to break anything else, and am desperate to restore Kmymoney4.
I’ve considered uninstalling gpgme @1.7.0_0 (which is active) and reinstalling it, but would appreciate some advice before
making a bigger mess of things.

Thanks in advance,

Stan
