[Q] Porting asterisk to Linksys WRTP54G router

The Linksys RTP300/WRTP54G routers and PAP2v2 are all based on a TI AR7 chipset. There has been some Work-in-Progress to port OpenWRT firmware to the AR7 platform for quite sometimes and never fruitfull. I am in a need to port and run an asterisk on my Linksys WRTO54G router. For this, I tried the TI-toolchain that I extracted from a Linksys WAG54GV2 firmware source I downloaded from a Linksys FTP site a las the compilation can not proceed because of missing ncurses and termcap libraries. I rebuilt these two libraries and am still not able to finish compiled asterisk for AR7, i.e. errors on final linking stage. I wonderd if anyone out here has managed to port/compile asterisk source code to an AR7 platform. If so, can you please help?
