I am attempting to compile 0.47 on Slackware 13.0.  I run configure then hit a snag: 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 downloaded the code from the URL mentioned above, it compiles fine.  Then I try to compile Inkscape, and it still gives me the above error. I did "make uninstall" on the gc package and downloaded the exact 6.4 package.  Compiled it...still no joy. Uninstalled that. Went to Slacky.eu and downloaded a precompiled gc 7.1 and installed that... Still getting the same error. What am I doing wrong?  Is it looking for some sort of development headers?  If so...whereinheck do I get those?
