Narrative:

Taxiing-in after landing mmpr; given instructions to taxi via a and east to ramp; spot X. Proceeded as instructed however ground advised us we had missed our turn onto east; hold position. No other traffic noted to be moving on taxiways or ramp area. Both first officer and I unclear on problem until the entrance taxiway; east; as we had reviewed and planned was signed with F. The chart we were using is still in the lep but is very much out of date. We discovered that on the chart; D is really east; and east is really F. Also; there is a new terminal in the center of the ramp and that spot X is on the new terminal; not to the far north end of the ramp. Tower was not overly concerned and seemed unaware that our charts were so incorrect. The event occurred; in my opinion; because a terminal that had been operational for 'at least 6 months' (according to a gate agent) and airport designations had not been updated. How this mess could be happening for so long precludes a rational reason why this is the situation.callback conversation with reporter revealed the following information: reporter stated these changes have existed for at least six months and perhaps as long as a year. It is very disconcerting for flight crews to find that their charts do not accurately reflect the actual airport layout.
