I'm the maintainers of these packages. A long time is passed after the
last submission, I will update them as soon as possible. Unfortunately at
the moment I can't test the build in Slackware 32-bit (running on a VM) due
a problem with the connection from the host after a new installation. I 
have to
this issue.
These packages do not depend on qt6, but depends on openmpi that after the
update to version 5 is not more compatible with 32 bit systems. This 
should be
solved changing the info file setting openmpi4 instead of openmpi but I 
have to
test it to be sure that this remove any problems. At the moment I could 
send
another submission setting UNSUPPORTED for Slackware 32-bit until I will
solve my problems in the virtual machine.
