Ok, I do not use windows more than a year now exactly because of 
problems like these, but this bug was often because of incorrect or 
missing value in extra-ghci-libraries attribute. Run this:
 ghc-pkg describe glib
and then check whether attribute extra-ghci-libraries contains something 
sensible. Now, I do not know what it needs to be exactly now (do not use 
windows any more so I cannot look it up) but I recall that I was adding 
value libcairo-2 to extra-ghci-libraries for the cairo package. The 
point is that the dll name containing the C implementation of the given 
package must correspond to the string in extra-ghci-libraries. IIRC, 
sometimes, I was also adding the path to the library (something like 
-L<path>) in ld-option attribute. But that was probably for compiling 
and not for ghci.

Hope it helps,
