[Ntop] configure issues

[Frank Clatterbaugh]

I have just downloaded the most recent version from CVS and am having difficulty compiling the source. I looked through the back traffic and couldn’t find the answer to this question, so be kind Burton.   When I run  configure I get the following errors: checking for libpng... checking png.h usability... yes checking png.h presence... yes checking for png.h... yes checking for main in -lpng... no   ******************************************************************* * * ERROR: libpng header or library routines are missing *           (yes means it was found, no means it was not found) * *              png.h...yes *              png_read_info() in -lpng... * *>>> No way to proceed. * *???        Install libpng (and/or libpng-devel), check www.libpng.org *???    and Rerun ./configure * *******************************************************************   I tried reinstalling zlib and libpng but it still gave these errors. I tried the –with directives to point to /usr/local/lib and /usr/local/include and still got these errors. Any ideas ?
