>Description:
There is some problem related to appearance of -L/usr/lib on the command line, which causes different sqlite3 libraries to be linked in (in some cases, but not always). I see it with for example net/gupnp and www/firefox.

>How-To-Repeat:
=========== Actual outcome
USE_CWRAPPERS=yes
PREFER.pkgsrc=sqlite3

$ cd /usr/pkgsrc/net/gupnp && make install
[...]
$ ldd /usr/pkg/lib/libgupnp-1.0.so  | grep sqlite3
        -lsqlite3.0 => /usr/pkg/lib/libsqlite3.so.0
        -lsqlite3.1 => /usr/lib/libsqlite3.so.1

=========== Expected outcome

USE_CWRAPPERS=no
PREFER.pkgsrc=sqlite3

$ cd /usr/pkgsrc/net/gupnp && make install
[...]
$ ldd /usr/pkg/lib/libgupnp-1.0.so  | grep sqlite3
tnn@t3610:gupnp> ldd /usr/pkg/lib/libgupnp-1.0.so  | grep sqlite3
        -lsqlite3.0 => /usr/pkg/lib/libsqlite3.so.0

>Fix:
