This application has failed to start because wxbase26u_gcc_custom.dll was not found. Re-installing the application may fix this problem.
Add the .dll using the -l argument to pp. Specify the full path to the .dll, build the .exe again and repeat.
I had to add:
-l c:\\Perl\\site\\lib\\auto\\Wx\\wxbase26u_gcc_custom.dll -l c:\\Perl\\site\\lib\\auto\\Wx\\wxmsw26u_adv_gcc_custom.dll -l c:\\Perl\\site\\lib\\auto\\Wx\\wxmsw26u_core_gcc_custom.dll
