use the ODBM_File extension since more advanced NDBM_File works fine,

+=head1 Perl Fails Because Of Unresolved Symbol sockatmark
+
+If you get an error like
+
+ Can't load '.../OSF1/lib/perl5/5.8.0/alpha-dec_osf/auto/IO/IO.so' for module IO: Unresolved symbol in .../lib/perl5/5.8.0/alpha-dec_osf/auto/IO/IO.so: sockatmark at .../lib/perl5/5.8.0/alpha-dec_osf/XSLoader.pm line 75.
+
+you need to either recompile your Perl in Tru64 4.0D or upgrade your
+Tru64 4.0D: the sockatmark() system call was added in Tru64 4.0F, and
+the IO extension refers that symbol.
