cpp: "rlver.c", line 3: error 4036: Can't open include file 'readline/readline.h'. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Could not compile rlver.c. If you have installed the GNU Readline Library (libreadline.{a,so} and readline/readline.h, etc.) on directories for which your perl is not configured to search (refer the value of `ccflags' and `libpath' in the output of `perl -V'), specify the paths as follows; perl Makefile.PL --includedir=/yourdir/include --libdir=/yourdir/lib or perl Makefile.PL --prefix=/yourdir Note that the GNU Readline Library version 2.0 and earlier causes error here. Update it to version 2.1 and/or later. Read INSTALL for more details. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
