./tool/rbinstall.rb:468 is trying to reference shebang.sub! on command scripts destined for /usr/local/bin and that's failing.

Steps:
./configure --host="arm-xilinx-linux-gnueabi"
make
make install DESTDIR=../newramdisk_mnt
...
ruby --disable=gems -I/export/sata/home/apaterson/Xara/z_ZedBoard_Linux_sw/ruby-2.0.0-p0 -rarm-linux-eabi-fake ./tool/rbinstall.rb --make="make" --dest-dir="../newramdisk_mnt" --extout=".ext" --mflags="" --make-flags="DESTDIR=../newramdisk_mnt" --data-mode=0644 --prog-mode=0755 --installed-list .installed.list --mantype="doc" --install=all --rdoc-output=".ext/rdoc"

It probably occurs when an empty file exists under bin directory.
Do you have it?

[AndrewCPaterson (Andrew Paterson)]

There are no empty files in the bin directory:

The problem is still present in p195

[AndrewCPaterson (Andrew Paterson)]

It is because there is a zero length file in a subdirectory under bin. There needs to be protection against this in rbinstall.rb

rbinstall.rb: reject empty files

• tool/rbinstall.rb (install_recursive): add maxdepth option.
• tool/rbinstall.rb (bin-comm): limit depth of bindir and reject empty
  files. [ruby-core:55101] [Bug #8432]
