git clone compile errors on isnan

[Larry Evans]

   Following directions here:
https://www.libreoffice.org/about-us/source-code/
   cloned libreoffice source:
Welcome to the Emacs shell

   ~/dwnlds/LibreOffice $ git clone git://anongit.freedesktop.org 
/libreoffice/core libreoffice

   then, following instructions later on here:

https://www.libreoffice.org/about-us/source-code/

   did some apt-get's:

sudo apt-get build-dep libreoffice
sudo apt-get install libgnome-vfsmm-2.6-dev

   the latter failed because:

E: Unable to locate package libgnome-vfsmm-2.6-dev
E: Couldn't find any package by glob 'libgnome-vfsmm-2.6-dev'
E: Couldn't find any package by regex 'libgnome-vfsmm-2.6-dev'

   Then, did the ./autogen.sh followed by make; however, the make
   resulted in several errors.  Did I clone the wrong git?

Here's the compile errors:
