and the log file:

error (RuntimeException): python-loader:exceptions.ImportError: No

the culprit is in some perl build scripts, leading to the obscure failure:

sub suck_setup($)
{
    my $file = shift;
    if (-f $file) {
        print "Reading setup from $file\n";
        open ($Vars, ". $file ; set|") || die "Can't find $file: $!";
        while (<$Vars>) {
            /([^=]*)=(.*)/ || next;
            $setup_vars{$1} = $2;
        }
        close ($Vars);
        return 1;
    }
    return 0;
}

apparently dash does quotes all the values of variables, even if quoting
is unnecessary. OOo relies on that, for example when constructing
PYTHONPATH :-/ Fixing that in the script:

        open ($Vars, "bash -c '. $file ; set'|") || die "Can't find
$file: $!";

Apparently perl always executes shell scripts using /bin/sh and doesn't
use the SHELL environment variable at all.

Checked in the patch below; Ubuntu doesn't seem to be the only
distribution using dash/ash as the system shell, so I'm wondering why it
doesn't break on other systems.
