Yesterday, I took the plunge and installed 3.6.6 on a brand new install of Ubuntu 12.04 server. Everything went swimmingly well ('restored' an old Koha db, data conversion succeeded) until: koha@sandbox:/usr/share/koha/bin/migration_tools$ KOHA_CONF=/etc/koha/koha-conf.xml PERL5LIB=/usr/share/koha/lib perl rebuild_zebra.pl -b -r -v -x ........

Could someone please tell me what the patch might be? (and possibly point me to what and where to create?) For the record, when I installed 3.6.1 (our production machine) earlier this year, this error did not occur. The only slight difference [not relevant?] was that I used Ubuntu 11.10 (12.04 had not been released), and that this time I did install a memcache server prior to Koha (I installed it after Koha was running on the production box.)
