Compile Error Can't Find Project Or Library Excel Mac

Using version 4.1.2, I keep getting the following error when I run my program on a Mac (I've tried two different systems, one 32 and one 64)

'Compile Error: Can't Find Project or Library'
The error is triggered by these lines (and possibly more, I didn't do an exhaustive review):

• Public AsyncRequests as Dictionary
• Private web_pConverters as Dictionary
• Public function ParseUrlEncoded(Encoded as String) As Dictionary

Any idea what could be causing these errors?
Thank you so much for creating this program, it has saved countless hours at a small non-profit!

@ethanlowens I see you closed this issue. Did you find a workaround? I'm running into a similar issue coming out of the WebHelpers classes, specifically in:

'
' 3. Url handling
' '

'
' Join Url with /
'
' @example
' VB.net ' Debug.Print WebHelpers.JoinUrl('a/', '/b') ' Debug.Print WebHelpers.JoinUrl('a', 'b') ' Debug.Print WebHelpers.JoinUrl('a/', 'b') ' Debug.Print WebHelpers.JoinUrl('a', '/b') ' -> a/b '
'
' @param {String} LeftSide
' @param {String} RightSide
' @return {String} Joined url
'
Public Function JoinUrl(LeftSide As String, RightSide As String) As String
If Left(RightSide, 1) = '/' Then
RightSide = Right(RightSide, Len(RightSide) - 1)
End If
If Right(LeftSide, 1) = '/' Then
LeftSide = Left(LeftSide, Len(LeftSide) - 1)
End If

Why doesn't my mac have a library folder download. End Function

FYI - when I looked at the references in the VBA editor there was a package was showing as 'MISSING' in the list. When I unchecked it, my code ran wihtout errors.
