Yes, it's a known problem, unless other solution is found, php will have to depend on libpng if gd use flag is set.
I have the the same problem. It should be solved by USE="zlib". But it wil fail on configuration: configure: error: ZLIB extendion requires zlib >= 1.0.9 I have got zlib-1.2.3, so this ain't right.

This bug is about USE="-png" emerge dev-lang/php failing at zlib check, not about misdetecting your zlib version. File a new bug.
This was now fixed in the PHP Overlay [1], after further investigation we found out that png and jpeg support is not optional, the GD extensions requires it unconditionally and if you disable it, it fails during compilation since it always wants to compile gd_png.c and gd_jpeg.c, so now the "gd" USE flag automatically enables both JPEG and PNG support in the background and requires the required libraries. Please test the PHP Overlay ebuilds if you want, they should go into official Portage tree during the next week. Best regards, CHTEKK. [1] http://svn.gnqs.org/projects/gentoo-php-overlay/
Please, test and report back if you still have problems.
I tried the for-portage 5.0.5-r1 and 5.1.0_rc1 ebuild, and they both work ;) checking for GD support... yes checking for the location of libjpeg... /usr checking for the location of libpng... /usr checking for the location of libXpm... no checking for FreeType 1.x support... no checking for FreeType 2... /usr checking for T1lib support... /usr checking whether to enable truetype string function in GD... yes checking whether to enable JIS-mapped Japanese font support in GD... no checking for fabsf... yes checking for floorf... yes checking for jpeg_read_header in -ljpeg... yes checking for png_write_image in -lpng... yes If configure fails try --with-xpm-dir=<DIR> checking for T1_StrError in -lt1... yes Unfortunately I don't have any gd-powered scripts lying around, so I can't test the binaries.
The changes work and were verified on several systems, closing. Best regards, CHTEKK.
