'make' is failing due to _iconv_close symbol missing

I am building from source on Mac OS 10.5. I have successfully built Apache and MySQL, but PHP is giving me difficulties. Configuration goes without any problems: ../configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-apxs2=/usr/local/apache/bin/apxs --with-zlib=/usr --with-iconv-dir=/usr But when I do a make I get the following error (sorry it's a big line): Undefined symbols: "_iconv_close", referenced from:

ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [libs/libphp5.bundle] Error 1 I have checked that the libiconv library is present in /usr/lib. I have even tried building the latest libiconv. Neither of these have resulted in getting past this error. I'm not sure how to proceed. Dale Hopkins
