[PPL-devel] Threes scripts in ppl 0.10.2 that need to be tweaked for Solaris

Minor annoyance but trivial to repair.

The following scripts all should refer to /bin/bash as the shell to execute in. The two utils will fail on Solaris as the "read" function fails with a note about the '-r' option being incorrect. This occurs because the read may be /usr/xpg4/bin/read or it may be /usr/bin/read where the base shell seems to solve all this with an internal function.

Thus :

$ diff configure configure.backup 1c1 < #!/bin/bash ---

#! /bin/sh

$ diff utils/cm_cleaner.sh utils/cm_cleaner.sh.backup 1c1 < #!/bin/bash ---

#!/bin/sh

$ diff utils/cm_splitter.sh utils/cm_splitter.sh.backup 1c1 < #!/bin/bash ---

#!/bin/sh
