libextractor on Solaris

Hello,

I just tried to build libextractor on Solaris and get
a linker error:

/bin/sh ../../libtool --mode=link gcc  -g -O2  -o
extract  extractor.o extract.o
../../src/main/libextractor.la -lm
gcc -g -O2 -o .libs/extract extractor.o extract.o ../../src/main/.libs/libextractor.so -lm -R/usr/local/lib
Undefined                       first referenced
 symbol                             in file
dlclose                             extractor.o 
(symbol belongs to implicit dependency /usr/lib/libdl.so.1)
dlsym                               extractor.o 
(symbol belongs to implicit dependency /usr/lib/libdl.so.1)
dlopen                              extractor.o 
(symbol belongs to implicit dependency /usr/lib/libdl.so.1)
dlerror                             extractor.o 
(symbol belongs to implicit dependency /usr/lib/libdl.so.1)
ld: fatal: Symbol referencing errors. No output
written to .libs/extract
collect2: ld returned 1 exit status

it seems that there's a problem with libtool (maybe outdated version?)
but i don't have the adequate environment on that box to play with it
(and i know little about libtool). Just reporting in case it's useful,
i can do more tests if you want.

or perhaps it's a bug in libtool. i don't know how to determine
