In the mean time I am trying to see why is happening this on my machine.
I guess it is happening because the library containg "sin" is not found; when 
I run configure I get the following message:

"checking for library containing sin... no",

BUT the configuration process does NOT complain in a "stop" manner (seems 
that this is not important so the configuration does not stop).
What should I do? What kind of library is this "libm" library? I do have 
libm.so.2.2.4 and a libm.so.6 which is a link to the first one on my system 
(RedHat 7.3), but seems that the "sim" symbol is not there.

Any ideea?

Thanks && Best regards,

PS: BTW brltty-3.0 had no errors at make time, BUT in 3.0 there is no 
configure, so I could not get the libbrlapi that I need.
