If for some reason you want to apply patch by hand rather than use prepared source tarball do this:

• download cvs source 1.10.8 (file: cvs-1.10.8.tar.gz) or any other later (or earlier) version and untar it to desired directory
• download cvs bookmarks patch (file: cvs-1.10.8-bookmarks.tar.gz) and place it inside cvs-1.10.8 directory
• change directory to cvs-1.10.8 and type:
  
  patch -p1 < cvs-1.10.8-bookmarks.patch
  
  
• do typical compile steps (e.g. ./configure ; make ; make install)
