Apparently this is because it was built with Perl 5.26.0, but
we've since moved to 5.26.1.
There's an open binnmu request at #883933 but I don't think that's the
correct way to fix this as it makes no provisions for partial upgrades.
I see two better alternatives:
1) [preferrable] fix polymake not to install its extensions in a
versioned directory (currently /usr/lib/polymake/perlx/5.26.0).
This may be as simple as
--- a/lib/core/src/perl/Makefile.PL
+++ b/lib/core/src/perl/Makefile.PL
@@ -140,7 +140,7 @@ WriteMakefile(
LIBS => "$libpaths $AddLibs",

INC => "-I$TOP/include/core",

+ LIB => "\$(InstallDir)/perlx",

but I haven't tested that (the package is huge...)
2) [less preferrable] add binnmu-safe strict dependencies on the current
Perl version. See for instance libdevel-cover-perl for an example of
how to do this. If you do this, please let p...@packages.debian.org know
so we can update
https://wiki.debian.org/PerlMaintenance#New_upstream_release_checklist
(and/or feel free to add to it yourself.)
I note that the confusing @INC list above (it has
/usr/lib/polymake/perlx/5.26.0 so it looks like it should work) is
because "use lib" will add versioned subdirectories to @INC if it
finds any, but will apparently *not* add arch-specific subdirectories
(like /usr/lib/polymake/perlx/5.26.0/x86_64-linux-gnu-thread-multi)
under those, and that's what would be needed here. I'm not quite sure
if this is a glitch in lib.pm's handling of binary-compatible versions
($Config{inc_version_list}).
Hope this helps a bit,
