 I work with MacOs Catalina 10:15:1 and I have installed the related
 macports. When I try to install xmgrace or motifs, or gnuplot, I get the
 message:
 {{{
 Error: Requested variants "+perl5_28" do not match those the build was
 started with: "+perl5_26".
 Error: Please use the same variants again, or run 'port clean ossp-uuid'
 first to remove the existing partially completed build.
 }}}

 I have no idea how to solve this. It worked smoothly in the previous OS,
 like Sierra and high sierra.

 In addition the recommended 'port clean ossp-uuid' does not work for me.
 An I do not know how to modify which variants I am requested.
 Thank you a lot for your help, I am totally stuck with this.

Comment:

 `sudo port clean ossp-uuid` should fix the problem. If not, does running
 that command give you some kind of error message?
