I don't think I'm of much help since all I can say is it
works here, but I'll try anyway. :-)

I followed the same course to build svn and it still works
for me. I checked out fresh copy of Subversion tree and
manually applied --enable-dso patch.

I get this:

[penny@u svn]$ ls -l subversion/libsvn_ra/.libs/
total 95
-rw-rw-r-- 44532 Nov 26 16:53 libsvn_ra.a

It looks like libtool is not working correctly. I don't
have 'U' appended to library name and have no link error. I
think 'U' is the cause of the problem but I don't know why
it occurs and I don't know how to fix it. :-(

The only cause I remember is that the BerkelyDB library is
not on your LD_LIBRARY_PATH or /etc/ld.so.conf but it's not
likely in your environment.

Hmm. I'm using exactly the same tool (Debian unstable,
right?). Weird.

[penny@u svn]$ libtool --version
ltmain.sh (GNU libtool) 1.4.2 (1.922.2.53 2001/09/11 03:18:52)
