>Description:
        the default setup of the GD library links with -lpthread, and
        perl58 does not.  
        When building pkgsrc/graphics/p5-GD, as soon as loading the GD
        module, perl core dumps (due to thread<->non-thread mismatch)
        This happens on i386, sparc, sparc64 architecture.
>How-To-Repeat:
        install pkgsrc/lang/perl58
        install pkgsrc/graphics/gd  (plus dependencies)
        go to pkgsrc/graphics/p5-GD
        run "make PKGSRC_RUN_TEST?=yes"
>Fix:
        the workaround I used was to build graphics/gd without freetype
        support and without linking with -lpthread (removing the 
        BUILDLINK_DEPENDS statement and the #.include of 
        ".../freetype2/buildlink3.mk" and ".../pthread.buildlink3.mk" 
        from both gd/Makefile and gd/buildlink.mk) - but this looses 
        freetype functionality 

        Another workaround that was discussed in tech-pkg was to always
        link perl58 with "-lpthread".

        One thing that should be done in any case is to check for 
        collisions (threaded GD <-> unthreaded perl) to tell the user
        what's going on instead of just core dumping on him.
