Hello, I'm having issues with compiling ion3 with my new Mac Pro. The configure script seems to be unable to locate X11/SM/SMlib.h. I have Apple's X11 installed and SMlib.h clearly exists in the proper location. I already have ion3 installed through MacPorts on both my MacBook and Mac Mini with similar setups and did not encounter this problem. Has anyone else come across this issue or know how to fix it? My logs are attached below. -- Mark monaco(~) [465] % sudo port install ion3 ---> Configuring ion3 Error: Target com.apple.configure returned: configure failure: shell command "cd "/opt/local/var/db/dports/build/_opt_local_var_db_dports_sources_rsync.rsync.darwinports.org_dpupdate_dports_x11_ion3/work/ion-3ds-20060524" && CPPFLAGS="-I/opt/local/include" LDFLAGS="-L/opt/local/lib" ./configure --prefix=/opt/local --disable-shared --with-lua-libraries=/opt/local" returned error 1 Command output: checking for a BSD-compatible install... /usr/bin/install -c checking for ranlib... ranlib checking for strip... strip checking for ar... ar checking for xmessage... xmessage checking how to run the C preprocessor... gcc -E checking for X... libraries /usr/X11R6/lib, headers /usr/X11R6/include checking for gethostbyname... yes checking for connect... yes checking for remove... yes checking for shmat... yes checking for IceConnectionNumber in -lICE... yes checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking libintl.h usability... yes checking libintl.h presence... yes checking for libintl.h... yes checking X11/SM/SMlib.h usability... no checking X11/SM/SMlib.h presence... no checking for X11/SM/SMlib.h... no configure: error: *** SMlib.h not found. *** You probably need to install libsm-dev Error: Status 1 encountered during processing. - monaco(/usr/X11R6/include/X11/SM) [472] % ls -l total 48 -r--r--r-- 2 root admin 2986 Dec 5 01:42 SM.h -r--r--r-- 2 root admin 11324 Dec 5 01:42 SMlib.h -r--r--r-- 2 root admin 4916 Dec 5 01:42 SMproto.h
