A flaw in the v8.0 loadLSST scripts (and/or in eups/bin/setups) causes the following errors:
1) When using ksh:
And indeed, there is no eups/bin/setups.ksh file.
2) When attempting to run the installation demo (v184.108.40.206):
[The same issue appears with csh, unsurprisingly.]
After hand-editing the demo.sh script to omit the "/default" string from the offending line, the demo runs normally to completion.
Note that everything works fine for bash with v8.0, which is what I tested awhile back.
