Note that doing a Super Search for articles that mention LD_LIBRARY_PATH might have gotten you enough information to get past this problem. I didn't find the answer neatly wrapped up (but I only looked at a couple of the hits), though, so here is one...
You likely can't set LD_LIBRARY_PATH from within the running process no matter how early you do it as the linker/loader has already started loading the process and has cached the value of LD_LIBRARY_PATH. Previously I've work around this by execing the perl executable so that it must reload and will see the new LD_LIBRARY_PATH that I have set. On some operating systems, even that isn't enough as the linker/loader notices that we are execing the same executable and doesn't bother to reinitialize. For such cases, you have to exec a different executable and ask it to exec perl for you.
Something close to the following should work:
BEGIN {
my $need= '/usr/local/sybase/lib';
my $ld= $ENV{LD_LIBRARY_PATH};
if( ! $ld ) {
$ENV{LD_LIBRARY_PATH}= $need;
} elsif( $ld !~ m#(^|:)\Q$need\E(:|$)# ) {
$ENV{LD_LIBRARY_PATH} .= ':' . $need;
} else {
$need= "";
}
if( $need ) {
exec 'env', $^X, $0, @ARGV;
}
}
