Simplified recipe:

svnadmin create repo1
svnadmin create repo2
svnmucc -mm -U file://`pwd`/repo1 \
  mkdir dir1 \
  put repo1/format dir1/file2
svnmucc -mm -U file://`pwd`/repo2 \
  propset svn:externals '^/../repo1 dir3' /
svnmucc -mm -U file://`pwd`/repo2 \
  propdel svn:externals / \
  mkdir dir3 \
  mkdir dir3/dir1

svn co file://`pwd`/repo2 wc
svn up -r1 wc
Updating 'wc':
D    wc/dir3
 U   wc

Fetching external item into 'wc/dir3':
A    wc/dir3/dir1
A    wc/dir3/dir1/file2
svn: warning: W155009: Failed to run the WC DB work queue associated with
'/home/pm/sw/subversion/obj/wc/dir3', work item 1 (file-install dir3/dir1/file2
1 0 1 1)

Updated to revision 1.

 U   wc

Fetching external item into 'wc/dir3':
