Thats not right. Of course, they don't support the nibs created with IB, 
the season for this is that the nib format is somewhat undocumented and 
contains some references to private Ivars of the classes that got 
serialized. GNUstep has a own format for that purpose, it is called 
.gorm like their IB Clone, the Graphical Objects Relations Manager. And 
there is a tool that converts .nibs to .gmodels (another format for that 
purpose understood by GNUstep). The reason GORM is not widely used is, 
that it is not finished yet, it is currently in alpha state but made 
great progress lately.
