debian guile-1.6.4 pkg and guile-1.6.5 manually installed lib problem

[David Pirotte]

Hello,

using debian, following packages installed

        address@hidden:/usr/local/lib/guile-pg/0.15 17 $ dpkg -l | grep guile
ii  guile-1.6                     1.6.4-4             ...
ii  guile-1.6-dev                 1.6.4-4             ...
ii  guile-1.6-doc                 1.6.4-4             ...
ii  guile-1.6-libs                1.6.4-4             ...
ii  guile-1.6-slib                1.6.4-4             ...
ii  guile-common                  1.4-26              ...
rc  guile1.4                      1.4-25              ...
ii  libguile-ltdl-1               1.6.4-4             ...
ii  libguile9                     1.4-26              ...
ii  libgwrapguile-dev             1.3.4-12            ...
ii  libgwrapguile1                1.3.4-12            ...


configured/compiled/installed guile-1.6.5 and 'which guile' tells me 
/usr/local/bin,
but

        1. guile --version says 1.6.4
        2. (use-modules (database postgres)) tries to load from /usr/lib 
instaead of /usr/local/lib


        address@hidden:~ 26 $ echo $GUILE_LOAD_PATH
/usr/local/share/guile:/usr/local/share:/usr/local/lib:/usr/local/pgsql/lib:/usr/lib:/usr/alto/projects/guile:/usr/share:/usr/share/slib


any hints on this?
thanks
david
