Alright.  It is not plperl folks fault, shared libraries and binaries do
things differently.  Consider:

$ cat >binary.c
int main() {}
^D

$ gcc binary.c -Wl,-E -L/usr/local/lib \
    /usr/local/lib/perl5/5.6.2/mach/auto/DynaLoader/DynaLoader.a \
    -L/usr/local/lib/perl5/5.6.2/mach/CORE -lperl -lm -lcrypt -lutil \
    -o binary

$ ldd ./binary
./binary:
        libperl.so => /usr/lib/libperl.so (0x28066000)
        libm.so.2 => /usr/lib/libm.so.2 (0x280fe000)
        libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x28119000)
        libutil.so.3 => /usr/lib/libutil.so.3 (0x28132000)
        libc.so.4 => /usr/lib/libc.so.4 (0x2813b000)

$ cat >lib.c
int hello() { return 0; }
^D

$ gcc -fpic -DPIC -shared -Wl,-x,-soname,liblib.so.0 lib.c \
    -Wl,-E -L/usr/local/lib \
    /usr/local/lib/perl5/5.6.2/mach/auto/DynaLoader/DynaLoader.a \
    -L/usr/local/lib/perl5/5.6.2/mach/CORE -lperl -lm -lcrypt -lutil \
    -o liblib.so.0

$ ldd ./liblib.so.0
./liblib.so.0:
        libperl.so => /usr/lib/libperl.so (0x28105000)
        libm.so.2 => /usr/lib/libm.so.2 (0x2819d000)
        libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x281b8000)
        libutil.so.3 => /usr/lib/libutil.so.3 (0x281d1000)

Now, with -R things a-changing:

$ gcc -fpic -DPIC -shared -Wl,-x,-soname,liblib.so.0 lib.c \
    -Wl,-E -L/usr/local/lib \
    /usr/local/lib/perl5/5.6.2/mach/auto/DynaLoader/DynaLoader.a \
    -L/usr/local/lib/perl5/5.6.2/mach/CORE -lperl -lm -lcrypt -lutil \
    -R /usr/local/lib/perl5/5.6.2/mach/CORE \
    -o liblib.so.0

$ ldd ./liblib.so.0
./liblib.so.0:
        libperl.so => /usr/local/lib/perl5/5.6.2/mach/CORE/libperl.so (0x28105000)
        libm.so.2 => /usr/lib/libm.so.2 (0x281ca000)
        libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x281e5000)
        libutil.so.3 => /usr/lib/libutil.so.3 (0x281fe000)

I am not that proficient with ld.so to know why it is like that, but the
easiest thing would be to persuade plperl to add that -R somewhere.
