[Libguestfs] Building from source with custom gperf location
Thanks Rich, that worked. I also had to compile augeas and specify 'AUGEAS_LIBS=~/.local/lib AUGEAS_CFLAGS="-O3"' for it to be picked up. The problem I'm hitting now is: configure: error: libmagic (part of the "file" command) is required. Please install the file devel package I have manually installed the contents of the file-devel RPM and its dependency file-libs into ~/.local/, so I now have libmagic.so under ~/.local/lib64/. Any idea how I can get ./configure to pick this up? I tried LD_LIBRARY_PATH=~/.local/lib64 but this didn't seem to work. I'm hopeful this might be the last piece that's missing!

Unfortunately m4/guestfs-libraries.m4 is using AC_CHECK_LIB instead of PKG_CHECK_MODULES, so you cannot just set PKG_CONFIG_* environment variables to pick up the right libmagic.pc (which is a bug in libguestfs).
