Dumpcap depends on wsutil.so. The path to the shared library is encoded in the RPATH (or RUNPATH) property of ELF binaries. This is currently an absolute path on most Unixy systems. Dumpcap could not be made to work with a relative RPATH because it uses elevated privileges and some loaders will ignore relative RPATHs and non-standard paths under those circumstances, because of (justified) security concerns. To enable relocation of the program we link dumpcap statically with wsutil instead. This provides a fully working relocatable installation on Linux and other platforms that support relative RPATHs.
