Mix together flour and salt. make well in center. put pumpkin and 1 tbsp water in the well. Slowly incorporate the wet into the dry making a rough dough and adding more water as needed. (I have done this with a bread hook on my kitchen aid mixer as well)
Turn the dough onto a floured surface and knead into a smooth dough. (about 5 mins) The dough should not break apart or crack. (You might have to wet your hands if the dough gets too dry)
Roll into log and wrap in a clean, damp towel. Set aside for 20 minutes
Roll out to an even thickness of 1/8 inch or less. Cut into desired shapes, (linguine, squares for pot pie,etc) or add filling (I use cream cheese, with chives and canned chicken or ground, seasoned pork) and seal for ravioli or tortellini, etc.
boil just as you would any other fresh pasta, cover with your choice of sauce and enjoy!
