Re: BUG #4219: fseeko test failure in configure script

Tom,
    LD_LIBRARY_PATH is the correct env var to use.  However, you are
correct that this hamstrings the generated executable - requiring
that the LD_LIBRARY_PATH include all of the shared object libraries
in the rc scripts themselves.

    Regarding the possibility of a bug, I had indicated that I
performed the ld command from the command in the postgres build area
and did not have an error returned.  Here is the listing of the ssl
lib area (done with pkgadd):

# cd /usr/local/ssl/lib
# ls -l
total 9004
-rwxrwx--x   1 root  root        1540 Jun  5 08:49 a.out
drwxr-xr-x   2 bin   bin          512 Jun  3 11:15 engines
-rw-r--r--   1 bin   bin      2290290 May 30 02:54 libcrypto.a
lrwxrwxrwx   1 root  root    18 Jun  3 11:15 libcrypto.so -> libcrypto.so.0.9.8
-r-xr-xr-x   1 bin   bin      1559648 May 30 02:54 libcrypto.so.0.9.8
-rw-r--r--   1 bin   bin       404896 May 30 02:54 libssl.a
lrwxrwxrwx   1 root  root          15 Jun  3 11:15 libssl.so -> libssl.so.0.9.8
-r-xr-xr-x   1 bin   bin       302776 May 30 02:54 libssl.so.0.9.8
drwxr-xr-x   2 bin   bin          512 Jun  3 11:15 pkgconfig

The links are there from libssl to the specific shared object lib and
all of the packages I added were built using the gcc compiler.
