Comment 2 for bug 498660

An update on this. I built the xtrabackup binary using the source code using mysql-5.1.34.tar.gz (source) and the xtrabackup-1.0.tar.gz (source). I used the build script: xtrabackup-1.0/innobase/xtrabackup/utils/build51tree.sh

The build failed while compiling xtrabackup, so I had to edit the xtrabackup-build/mysql-5.1.34/storage/innobase/xtrabackup/Makefile to comment out the MySQL 5.0 build instructions and uncomment the MySQL 5.1 build instructions. Then ran make to finish the building. Using this binary against a database with barracuda compressed tables I ran into the exact same errors as with the RHEL 5 binary RPM released by Percona built against MySQL 5.0. Here is the output:

./xtrabackup --backup --target-dir=/backup --innodb_file_per_table

Let me know if you need any more information. Perhaps my build method was flawed.
