When I try to configure Inkscape 0.44, I get a message:
checking gc.h usability... yes
checking gc.h presence... yes
checking for gc.h... yes
checking for GC_init in -lgc... yes
checking libgc version 6.4+... 6.3.255 no
configure: error: libgc (the Boehm Conservative Collector) 6.4+, is needed to compile inkscape -- http://www.hpl.hp.com/personal/Hans_Boehm/gc
I have libgc 6.7 installed, so I'm not certain why Inkscape doesn't like it. Any ideas?
