Roderich,
You are correct e88b1fb1.xs.dll is identical to PNG.xs.dll but what that
means is:
[james.r@jrushworth PNG]$ objdump -ax PNG.xs.dll | perl -ne 'print if
/DLL Name/'
DLL Name: msvcrt.dll
DLL Name: libpng16-16__.dll
DLL Name: KERNEL32.dll
DLL Name: perl524.dll
C:\Users\james\AppData\Local\Temp\par-6a616d6573\cache-c1546264452e74db829440ed61c603745f7769ed>objdump
-ax e88b1fb1.xs.dll | perl -ne "print if /DLL Name/"
DLL Name: msvcrt.dll
DLL Name: libpng16-16__.dll
DLL Name: KERNEL32.dll
DLL Name: perl524.dll
objdump for both files shows exactly the same links.
The original error message tells us that it can't find e88b1fb1.xs.dll
but the same file is in the executable called PNG.xs.dll. Why is it able
to find the file if Strawberry Perl is installed on the machine but not
if it isn't. One of the things I tried is installing Strawberry Perl on
the machine immediately after getting the error message and starting a
new command prompt with Strawberry Perl in the path and having the
executable run with no error.
