I have started looking into this. The right fix is for po4a Sgml module 
to support translating attributes. I guess it has not been done yet 
because it's only useful for one attribute: lang. The problem is that 
this is not supported at all and I'm a bit lost as to how to modify it. 
It looks like it should be done near this code (line Sgml.pm:680):

if ($val->type() eq 'CDATA' ||
                     $val->type() eq 'IMPLIED') {
                     if (defined $value && length($value)) {
                         if ($value =~ m/"/) { #"
                             $value = "'".$value."'";
                         } else {
                             $value = '"'.$value.'"';
                         }
                         $tag .= ' '.lc($attr).'='.$value;
                     }

They can't because the generated file depends on two source files and 
not just one. At least for this rule (but maybe you were thinking about 
another one):

%.posgml: $(SGMLDIR)/%.sgml %.po

Why is this not good?

This itself is going to be annoying.

It looks like perl is being run in a French locale. Is this your doing 
or po4a's?

po4a depends on the gettext perl module. It's a standard Perl module so 
there should be an RPM for it. What's ironic is that this is just so 
po4a can issue localized error messages, AFAIK it's not needed for po4a 
to perform its work.
Once this is fixed you may find that you have to install the SGMLS perl 
module but po4a should give you a nice error message. That should be all 
of po4a's requirements I think.

Note that to compile the SGML sources you also have to install a bunch 
of packages (docbook, docbook-dsssl, jade, etc). po4a only adds two 
extra packages to the list which should not be too bad. We could also 
detect that the Perl packages are missing in the configure script and 
either issue an error message or disable the compilation of translated 
documentation. It's up to you.
