That looks like it's complaining about permissions on your "myprojects" directories. I take it you've tried checking that you have permission to write a file to "myprojects/.bzr/branch/lock", for example:
$ touch myprojects/.bzr/branch/lock/test-file
$ ls -l myprojects/.bzr/branch/lock/test-file
If it's not a permissions problem you could try the `bzr break-lock` option, for help on it see `bzr help break-lock`
