[Ekiga-list] compile error with ptlib cannot find

[Yang Xiao <treverxiao gmail com>]

Hi
I had below error when I try to ./configure --prefix=/usr or
PKG_CONFIG_PATH=/usr/lib/pkgconfig ./configure --prefix=/usr. Please
help.

besides, I have successfully installed ptlib 2.6.7.

ERRER LOG:
checking for PTLIB... configure: error: Package requirements (ptlib >=
2.6.6) were not met:

No package 'ptlib' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables PTLIB_CFLAGS
and PTLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
