This can be built on EL10 with the following steps:
1: Install Dependencies:

dnf groupinstall -y "Development Tools" 
dnf install -y \
    fdupes \
    perl \
    perl-Carp \
    perl-CPAN-Changes \
    perl-doc \
    perl-Encode-HanExtra \
    perl-Exception-Class \
    perl-Exporter \
    perl-ExtUtils-MakeMaker \
    perl-FileHandle \
    perl-File-Slurp \
    perl-generators \
    perl-interpreter \
    perl-IO \
    perl-libs \
    perl-Pod-Perldoc\
    perl-Readonly \
    perl-Socket \
    perl-Sort-Naturally \
    perl-Sys-Hostname \
    perl-Test-Differences \
    perl-Test-DistManifest \
    perl-Test-Pod \
    perl-Test-Pod-Coverage \
    perl-Test-Trap \
    perl-Tk \
    perl-XML-Simple \
    perl-vars \
    perltidy \
    xterm \
    rpm-build

2: Build the perl-X11-Protocol rpm from the EL9 source rpm (perl-X11-Protocol-0.56-42.el9.src.rpm)

rpmbuild --rebuild perl-X11-Protocol-0.56-42.el9.src.rpm

3: Install newly built EL10 perl-X11-Protocol rpm

yum localinstall perl-X11-Protocol-0.56-42.el10.noarch.rpm

4: Build the perl-X11-Protocol-Other rpm from the EL9 source rpm (perl-X11-Protocol-Other-31-12.el9.src.rpm)

rpmbuild --rebuild perl-X11-Protocol-Other-31-12.el9.src.rpm

5: Install newly built EL10 perl-X11-Protocol-Other rpm

rpmbuild --rebuild perl-X11-Protocol-Other-31-12.el9.src.rpm

6: Build the clusterssh rpm from the EL9 source rpm (clusterssh-4.18-1.el9.src.rpm)

rpmbuild --rebuild clusterssh-4.18-1.el9.src.rpm

This will produce a working EL10 rpm (clusterssh-4.18-1.el10.noarch.rpm)

Depends on:

https://bugzilla.redhat.com/show_bug.cgi?id=2427428  (EL10 build of perl-X11-Protocol)

https://bugzilla.redhat.com/show_bug.cgi?id=2427430  (EL10 build of perl-X11-Protocol-Other)

Both of the perl dependency tickets have been submitted as updates for the 10.1 and 10.2 repos.

hi, thanks for your updates, I'm on vacation and abroad for next 4-weeks, will take care when I fly back home.

There may need to be an additional update to get it fully working.
 
> cssh foo.host.sys
Connection to server failed -- (version 11.0)
authorization required, but no authorization protocol specified
at /usr/share/perl5/vendor_perl/App/ClusterSSH/Window/Tk.pm line 57.

Looks like cssh is attempting to create an xwindow with a call to "X11::Protocol->new()".  Looks like X on EL10 by default is blocking those kinds of connections.
 
 
To work around:
 
Install the xhost rpm.
 
Then run the following command in your graphical shell environment.
 
xhost + si:localuser:YOURUSERNAME
 
(replacing YOURUSERNAME with your actual user name)
