Hi, currently gssdp links directly to gtk+ even if the configure.ac lets you specify if you want to use it or not (by now it only needs gtk for some tools, any gssdp core functionality depends on gtk).
Would be nice to not be able to have to install also gtk and all their dependencies. I would be willing to update the .ebuild but I lack knowledge, any pointer? :)
Do you by chance mean net-libs/gssdp ?
Uh, sorry yes, net-libs/gssdp :)
