building libwww under solaris 2.6

Hello

I try to build libwww under solaris 2.6 but it doesn' t work.
"./configure" works goods but I have error with "make" : 
--->
make[4]: Entering directory `/slave/home/oscar/download/w3c-libwww-5.4.0/modules/expat/xmltok'
/bin/sh ../../../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../../..     -g -O2 -Wall -DXML_NS -c xmlrole.c
../../../libtool: test: argument expected
make[4]: *** [xmlrole.lo] Error 1

Using "./configure --without-expat", I've got the same probleme with md5

Can anyone help me please?
