>Description:
Here is an edited log of a build of the devel/aegis port:

*** Error code 1
Stop in /usr/ports/devel/aegis.
In /usr/ports/devel/aegis/work/aegis-4.24/common/config.h:
/* Define to 1 if you have the `strverscmp' function. */
#define HAVE_STRVERSCMP 1
On the other hand if I:
cd /usr/ports/devel/aegis/work/aegis-4.24 && ./configure
.

checking for strverscmp... no

.
So, when running the ports "make configure" in /usr/ports/devel/aegis strverscmp() is (incorrectly) found, but when running the aegis-4.24 configure script in /usr/ports/devel/aegis/work/aegis-4.24 strverscmp() is (correctly) not found.
I am not familiar with GNU configure etc. so I hope you will bear with me in the following.
Further investigation shows that the ports "make configure" produces the following in work/aegis-4.24/config.log:
c++ -o conftest -O2 -fno-strict-aliasing -pipe -march=pentium4 -I/usr/local/include -I/usr/local/include/libxml2 -I/usr/local/include -I/usr/local/include -L/usr/local/lib conftest.cpp -lc -lxml2 -lcurl -lmagic -lcrypt -lbz2 -lz -lm -lintl -liconv >&5
On the other hand running work/aegis-4.24/configure produces the following in config.log:
g++ -o conftest -g -O2 -I/usr/local/include -I/usr/local/include
/libxml2 -I/usr/local/include conftest.cpp -lxml2 -lcurl -lmagic -lcrypt -lbz2
-lz -lm >&5
Note that the ports "make configure" output shows that the test program is compiled with "-lintl -liconv" whereas the command which fails in the actual build does not find a declaration of strverscmp. A search of /usr/local/include did not turn up a declaration of strverscmp().
Examining the configure script suggests that the test program looks something like this:
/* System header to define __stub macros and hopefully few prototypes,
which can conflict with char $ac_func (); below.
Prefer <limits.h> to <assert.h> if __STDC__ is defined, since
<limits.h> exists even on freestanding compilers. */
#ifdef __STDC__
# include <limits.h>
#else
# include <assert.h>
#endif
-lintl -liconv
#ifdef __cplusplus
extern "C"
#endif
char strverscmp();
int
main ()
{
return strverscmp();
}
Calling this tt.cpp and compiling it with:
c++ -o tt -O0 -g -fno-strict-aliasing -pipe -march=pentium4 -I/usr/local/include -I/usr/local/include/libxml2 -I/usr/local/include -I/usr/local/include -L/usr/local/lib tt.cpp -lc -lxml2 -lcurl -lmagic -lcrypt -lbz2 -lz -lm -lintl -liconv
then running gdb:

libidn.so.16 belongs to the port libidn-1.8_2 which depends on libiconv-1.11_1
SUMMARY:
During "make configure" of devel/aegis the ports system is including "-lintl -liconv". This causes the aegis-4.24 configure script to find a strverscmp(). Those libraries are not included in the actual build compile and link commands.
>How-To-Repeat:
Run "make" in /usr/ports/devel/aegis
>Fix:
A hack to allow the build to complete is to undefine HAVE_STRVERSCMP in /usr/ports/devel/aegis/work/aegis-4.24/common/config.h
