libunwind was not found. Try installing:
 * deb: libunwind-dev (Debian, Ubuntu, etc)
 * rpm: libunwind-devel (Fedora, EPEL)
 * from source: https://github.com/libunwind/libunwind
If libunwind is already installed, check that either:
'pkg-config' is in your PATH AND PKG_CONFIG_PATH contains
a libunwind.pc file.
If it cannot detect , you can set INCLUDE_DIR
and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Libraries have been installed in:
   /home/hornik/tmp/scratch/RtmpcXPW7P/R.INSTALL30889236a4dd36/winch/src/build/libbacktrace/../../local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
