|P is for Practical|
The two machines extract the files and compile in a different order, but it appears to be the same files and same compile commands. The only difference I see before the failed test is that one machine refers to dmake as C:\STRAWB~1\c\bin\dmake.exe, while the other refers to it as C:\Strawberry\c\bin\dmake.EXE.
A shortpath versus a longpath wouldn't/shouldn't make a difference if they're pointing to the same place
Yeah "appears to be" sounds very much like "doesn't work" ( vague) but
its windows, a debugger might provide more info
If it works on your version of windows (probably doesn't), try depends.exe Ctrl+O perl.exe , F7 ...foo.pl to see a LoadLibrary trace, might have more info
or from commandline depends.exe /c /f:1 /pb /ot:temp.txt ...perl.exe foo.pl
