I'm definitely not a shell scripting compatibility expert.
But one thing became clear: Bourne shell is slightly outdated. And not
everybody outside Sun has been maintaining backward compatibility. Once
I fixed the problem below I ran into the next one. And into the next
five. Then I looked for a better hack:
My "fix" is now to use bash.
The reason for all those unusual problems with mesalib is, that it
doesn't use SVR4-install, BSD-install nor GNU-install, but its own
intelligent shell script "minstall".
The workaround is now to just change that shell script's default shell
to /bin/bash.
$ file ./build_32/Mesa-6.5.2/bin/minstall
./build_32/Mesa-6.5.2/bin/minstall: executable /bin/bash script
...
- /bin/sh
+ /bin/bash
That solves a myriad of problems. As I use snv_70 I cannot test, if
ksh93 would work similarily good. But let's give ksh88 a try ... [testing]
--->> Yes, ksh88 works.
A 20 years old Korn shell is slightly more capable, than a 35 years old
Bourne.
I hope ksh93 will soon be symlinked to /usr/bin/sh.
Bourne should be mature for historic books and museums, but not for
being ZFS-os's system shell.
