shell script and rpm

["Phil Conan" <philconan hotmail com>]

Hi,

I am getting an error when using shell script within my rpm.
here is the script that fails within the rpm but works perfectly well
outside of the rpm:

if [ "${RPM_INSTALL_PREFIX}" = "%{prefix}" ] ; then
 # User has not used prefix do nothing
 echo "the prefix value is: ${RPM_INSTALL_PREFIX}"
else
  # User has used prefix
 echo "the prefix value is: ${RPM_INSTALL_PREFIX}"
 sed -e 's/usr\/local\/dsi\-0\.3/'$RPM_INSTALL_PREFIX'/g' /tmp/dsi_setup.sh 
>/home/telorb/dsi_setup.sh

the error after trying to install the rpm:
# rpm -i --prefix=/tmp dsi-0.3-1.i386.rpm
the prefix value is: /tmp
sed: -e expression #1, char 26: Unknown option to 's'
error: execution of %pre scriptlet from dsi-0.3-1 failed, exit status 1
error:   install: %pre scriptlet failed (2), skipping dsi-0.3-1

for some reason the rpm doesn`t like the single quote syntax I`m using for 
the variable '$RPM_INSTALL_PREFIX' when the sed is performed. any solutions?

this is rpm version 4.0.4 on RH7.3

thanks in advance,
Phil
