I've used your approach and was able to compile both mythtv and
mythplugins from SubVersion.  Take note that I changed my ld.so.conf to
match yours, and commented out the old lines.  I suspect that I need to
add back in the line from the howto below as I'm getting an error:

mythbackend: error while loaded shared libraries: libmythtv-0.20.so.0:
could not open shared object file: no such file or directory.

4.2 Shared-Library requirements for MythTV
Modifying /etc/ld.so.conf
The runtime manager for shared libraries, /lib/ld.so, gets information
about the locations and contents of shared libraries from
/etc/ld.so.cache, a file created by ldconfig from information in
/etc/ld.so.conf. Because MythTV installs some shared libraries in
/usr/local/lib, that directory needs to be added to the list of
directories for ld.so to search when doing runtime linking of programs, if
it is not already there. You do this, as root, by editing /etc/ld.so.conf,
then running ldconfig. There are many ways to do this; one that works is
to enter this series of commands:

$ su -
# echo /usr/local/lib >> /etc/ld.so.conf
# /sbin/ldconfig
# exit

Did you need to do this?
