Scripting seems broken loading gui

[Bruce Steers <bsteers4@xxxxxxxxx>]

this command...

echo -e 'Use "gb.gui"\nDim sRet As String\nShell "gambas3
--system-information" To sRet\nClipBoard.Copy(sRet,"text/plain")' | gbs3

this error.
[gb.gui.base]._Gui._InitApp.180: #2: Cannot load class 'MMain': File or
directory does not exist
[gb.gui.base]._Gui._InitApp.180 ?

Using "Use "gb.gui" in a script never used to error, now it does.

echo -e 'Use "gb.gui"\nMessage("Hi")'|gbs3 -
[gb.gui.base]._Gui._InitApp.180: #2: Cannot load class 'MMain': File or
directory does not exist
[gb.gui.base]._Gui._InitApp.180 ?
