Hi all * I have an error when trying to install the antigraingeometry package (version:2.5)

sudo port -ucv install antigraingeometry ---> Configuring antigraingeometry aclocal: configure.in: 103: macro `AM_PATH_SDL' not found in library Error: Target com.apple.configure returned: shell command "aclocal -I /usr/share/aclocal" returned error 1 Command output: aclocal: configure.in: 103: macro `AM_PATH_SDL' not found in library

Warning: the following items did not execute (for antigraingeometry): com.apple.activate com.apple.configure com.apple.build com.apple.destroot com.apple.archive com.apple.install Error: Status 1 encountered during processing. * The macro above looks something to do with libsdl, but libsdl is not listed as a dependent. I also have libsdl installed anyway. * Not really knowing what I'm doing I've tried editing the port file to use "aclocal -I /opt/local/share/aclocal" in place of the above (as sdl.m4 is in that directory) * This then has the following errors Portfile changed since last build; discarding previous state. ---> Fetching antigraingeometry ---> Verifying checksum(s) for antigraingeometry ---> Checksumming agg-2.5.tar.gz ---> Extracting antigraingeometry ---> Extracting agg-2.5.tar.gz ---> Configuring antigraingeometry configure.in:3: `automake requires `AM_CONFIG_HEADER', not `AC_CONFIG_HEADER' configure.in: installing `./install-sh' configure.in: installing `./mkinstalldirs' configure.in: installing `./missing' examples/Makefile.am:224: invalid unused variable name: `trans_curve2_ft_LDFLAGS' examples/Makefile.am:222: invalid unused variable name: `trans_curve2_ft_SOURCES' examples/Makefile.am:229: invalid unused variable name: `trans_curve1_ft_LDFLAGS' examples/Makefile.am:227: invalid unused variable name: `trans_curve1_ft_SOURCES' Error: Target com.apple.configure returned: automake failure: shell command "cd "/opt/local/var/db/dports/build/_opt_local_var_db_dports_sources_rsync.rsync.darwinports.org_dpupdate_dports_graphics_antigraingeometry/work/agg-2.5" && automake --foreign --add-missing --ignore-deps" returned error 1 Command output: configure.in:3: `automake requires `AM_CONFIG_HEADER', not `AC_CONFIG_HEADER' configure.in: installing `./install-sh' configure.in: installing `./mkinstalldirs' configure.in: installing `./missing' examples/Makefile.am:224: invalid unused variable name: `trans_curve2_ft_LDFLAGS' examples/Makefile.am:222: invalid unused variable name: `trans_curve2_ft_SOURCES' examples/Makefile.am:229: invalid unused variable name: `trans_curve1_ft_LDFLAGS' examples/Makefile.am:227: invalid unused variable name: `trans_curve1_ft_SOURCES' Warning: the following items did not execute (for antigraingeometry): com.apple.activate com.apple.configure com.apple.build com.apple.destroot com.apple.archive com.apple.install Error: Status 1 encountered during processing. * But this may be simply that I have no idea what I'm doing! d.
