I poked around the libraries with objdump, and found this difference:
jhbuilt libgnomevfs-2.so:
00000000         *UND*  00000000              SSL_new
Sun built libgnomevfs-2.so:
00000000       F *UND*  00000000              SSL_new

The objdump manpage says F indicates the symbol is the name of a function,
and a space indicates it's "just a normal symbol". So I guess it's some
linker option that's causing this. The Sun build [1] adds "-Wl,-zignore
-Wl,-zcombreloc -Wl,-Bdirect" to LDFLAGS, is one of these what sets the
function flag?

Ok, cc:ed gnome-love and opensolaris tools-discuss.
