I don't use bash but offhand I would say it's because cwspdpmi is not
in your path before you start bash ( config.sys is  processed before
autoexec.bat, where the PATH variable is specified).
Maybe copying cwsdpmi to the directory where bash resides? Or C:\ root?

If that doesn't work and you really need a dpmi host, try pmodetsr.exe,
a TSR dpmi host based on Tran's pmode extender and ported to djgpp.
It doesn't support virtual memory paging, so you might want to make
sure that enough RAM is available. Load it in your config.sys before
you start bash. Available from ftp://x2ftp.oulu.fi/pub/msdos/programming/djgpp2.

Or else fork out some $$ and buy QEMM (with QDPMI) which does support virtual
memory.
