Taskwarrior 2.4.2 came out a few days ago including mostly bugfixes. No changes are required to the ebuild other than renaming to match 2.4.2. Thanks Reproducible: Always

I can confirm - bump of 2.4.1 to 2.4.2 works (builds + runs as expected) just fine here.
In the meanwhile 2.4.3 has been released. Version bump for 2.4.3 #547896 In my opinion 2.4.2 can be skipped in favor of 2.4.3.
