Certainly. The svn:externals syntax even includes a shorthand for "this
repository"; use ^ in place of /path/to/repo.

For example, laying out your repo like this:

   /
   /libs
   /libs/lib1
   /libs/lib2
   /projects
   /projects/project1/
   /projects/project1/libs

Then you set svn:externals on /projects/project1/libs to

^/libs/lib1 lib1
^/libs/lib2 lib2

This allows you to have multiple projects that use shared libraries,
while avoiding having the library code duplicated inside each project.

Of course, you have to be careful when setting it up, as it can lead to
the recursive situation you ran in to.
