If you do not want to build Dr. MinGW's DbgHelp from source, you can place dbghelpdr.dll from a recent binary release of Very Sleepy (or Dr. MinGW, where it will be called mgwhelp.dll) into the dbghelp_x86 and dbghelp_x64 directories appropriately.
But I cannot find dbghelpdr.dll from a recent binary release of Very Sleepy (0.90, nor 0.82)
According to the readme.md:
