I don't know if this will work with our more commonly used ICL7660S although the pinout does appear to be the same. The schematic called for LT1054 which are more expensive, but I only paid about £5 for 5 on eBay a while ago and so they can still be had for a reasonable price without being fleeced too much. If you do want to try the ICL7660S then it may be worth omitting the cut between pins 1 and 8 to enable the frequency boost so you don't get noise. The LT1054's oscillator typically runs at 25kHz.
Using the 1N5817 diodes shown should give you around +/-17V, but if an effect calls for +/-15V then you could always opt for using 1N4001 diodes instead. The extra voltage drop will get you closer to 15V.
