The information from the shared library loader indicates the effects
to be expected from the output of the objdump command below.

the output of the objdump command is given below (actual output is one line!)

 # objdump -x subversion/svnversion/.libs/lt-svnversion | grep RPATH
 RPATH /home/erik/svn/subversion/libsvn_client/.libs:
/home/erik/svn/subversion/libsvn_wc/.libs:
/home/erik/svn/subversion/libsvn_ra/.libs:
/home/erik/svn/subversion/libsvn_ra_local/.libs:
/home/erik/svn/subversion/libsvn_repos/.libs:
/home/erik/svn/subversion/libsvn_fs/.libs:
/home/erik/svn/subversion/libsvn_ra_dav/.libs:
/home/erik/svn/neon/src/.libs:
/usr/local/lib:
/home/erik/svn/subversion/libsvn_ra_svn/.libs:
/home/erik/svn/subversion/libsvn_diff/.libs:
/home/erik/svn/subversion/libsvn_delta/.libs:
/home/erik/svn/subversion/libsvn_subr/.libs:
/home/erik/svn/apr-util/.libs:
/home/erik/svn/apr/.libs:
/usr/local/apr/lib

To see if the libtool command also contains the /usr/local/lib in the middle
of the list of libsvn_* libraries, I executed the command:

 # make LTFLAGS=

which gave as output (3 lines actual output):

creating svnversion

I have no idea what the output from libtool means with respect to resolving this problem though.

I figure this is a problem within the link stage of the program, maybe with the arguments from libtool for gcc?

Philip, do you know what my next step could be?

bye,

Erik.
