 Hi,

 I ran the configure script on AIX, and I get the error message:

 {{{
 tail: `-4' option is obsolete; use `-n 4'
 Try `tail --help' for more information.
 svn: Write error: Broken pipe
 }}}

 The issue is that "{{{tail -4}}}" in the line

 {{{
 svn info | tail -4 > $ac_default_prefix/src/version.txt
 }}}

 should be replaced by "{{{tail -n 4}}}"
