building php witk libiconv

Hi, I don't know what to do with libiconv to build php4.3.3. My libiconv-1.9 is installed in /opt if I invoke configure .... --with-iconv=/opt the script runs fine but I get the following message at compile time: gcc: /usr//lib/.libs/libiconv.so: No such file or directory gcc: /opt//lib/.libs/libiconv.so: No such file or directory What is strange is that /lib/.libs is a directory tree in the libiconv-1.9 source directory. So, I tried to invoke configure .... --with-iconv=/home/a.bonnefoy/portage/libiconv-1.9. But now configure complains asking me to reinstall libiconv. What to do??? Thanks, Alain.
