SWPM tool throws error during taking export in PPC64 based production system

Dear SAP BASIS Experts

Our motto is to take export from our production system. Our production system is based on PPC64 hardware. When we use 70SWPM10SP30_4-20009610.sar media to run sapinst, we are getting below error:

./sapinst: /lib64/power6/libc.so.6: version `GLIBC_2.7' not found (required by ./sapinst)

As per SAP Note 2679215, we use RMOS70SWPM10_12.SAR media to execute sapinst. But after running few screens, we are getting below error:

invalid message ID (PATH is not defined or have an empty value in environment : Properties)

Please advise how to proceed.
